Monetdb crashes.
Hello,
We have a main table with 126 columns and approx. 94000 rows. We are trying to load approx 2500 records from temporary table into main table using query “insert into select” query. The database crashes upon query execution.
We get error “*monetdbd: internal error while starting mserver, please refer to the logs*” when to try to connect again.
No specific error is created in log file. 1500 records successfully loads from temp table to main table. We also created another main table with same DDL, that table is empty & inserted all the records from temp successfully without any issue.
What could be the reason? Is 126 cols an issue? Please help. We are stuck.
(btw: We have machine about 200GB of hard disk & 16 GB RAM (14 GB free))
OS* - Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-55-generic x86_64)*
Monetdb version* - MonetDB v11.21.13 (Jul2015-SP2)*
Thank you

Dear Souri,
as both Hannes and Lefteris already mentioned with their replies to your earlier messages, we need detailed instructions (and data) how to reproduce the problem, otherwise, we have no means to debug it.
We easily operate tables with thousands of columns and millions of rows in MonetDB; hence, neither is expected to be a problem in general.
If your server crashes, and then fails to restart, this should be reflected in the merovingian.log . Please re-consult the log and feel free to share the relevant snippets.
If the server fails to restart and you fail to reconnect, how could you test with inserting fewer records into the very same table or inserting all records into a new empty table?
Best, Stefan

Hi Souri,
I checked the issue and I can confirm that something is happening with the copied data, and monetdb does not like it. This error occurs during the first copy into.
The error I get is server5: /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306: strPut: Assertion `(v[i] & 0x80) == 0' failed.
while trying to load the data. And the trace reads
#4 0x00007ffff72d4c8f in strPut (h=0x7fffbc14d640, dst=0x7fffd4aa3c80, v=0x7fffd4aa3dd0 "Leftover data '*data i am not sure i should share...(?)* "...) at /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306
So I suspect to be a parse error that is not treated as it is supposed to.
Can we use the main_schema, data, and queries you send me to open a bug report? or is it sensitive data? If we can use them, then I suggest you open a bug report for the correct person to see it and fix it.

Hi,
you can report the bug at https://www.monetdb.org/bugzilla/
You can do it yourself so you can now how to do it next time and have a quicker response from the monetdb team:)
In the meanwhile, what I can see is that the crash is because of a parse error. MonetDB should deal with that error without crashing, but once we fix that, the parse error will remain anyhow. I suspect that it is because of non-ascii wierd-utf(??) characters that your data have. You can either clean the data before importing or try to specify the correct encoding.
Hope this helps for now,
Lefteris

This indicates that there is a non-UTF-8 character in the input. Of course, there should not be an assertion error if wrong input is given, so that problem has been fixed in changeset c5460cc0b66b. What then remains is the bad input.

Dear Souri,
as both Hannes and Lefteris already mentioned with their replies to your earlier messages, we need detailed instructions (and data) how to reproduce the problem, otherwise, we have no means to debug it.
We easily operate tables with thousands of columns and millions of rows in MonetDB; hence, neither is expected to be a problem in general.
If your server crashes, and then fails to restart, this should be reflected in the merovingian.log . Please re-consult the log and feel free to share the relevant snippets.
If the server fails to restart and you fail to reconnect, how could you test with inserting fewer records into the very same table or inserting all records into a new empty table?
Best, Stefan

Hi Souri,
I checked the issue and I can confirm that something is happening with the copied data, and monetdb does not like it. This error occurs during the first copy into.
The error I get is server5: /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306: strPut: Assertion `(v[i] & 0x80) == 0' failed.
while trying to load the data. And the trace reads
#4 0x00007ffff72d4c8f in strPut (h=0x7fffbc14d640, dst=0x7fffd4aa3c80, v=0x7fffd4aa3dd0 "Leftover data '*data i am not sure i should share...(?)* "...) at /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306
So I suspect to be a parse error that is not treated as it is supposed to.
This indicates that there is a non-UTF-8 character in the input. Of course, there should not be an assertion error if wrong input is given, so that problem has been fixed in changeset c5460cc0b66b. What then remains is the bad input.
Can we use the main_schema, data, and queries you send me to open a bug report? or is it sensitive data? If we can use them, then I suggest you open a bug report for the correct person to see it and fix it.

The fix has not been ported to default? or a different issue?

Hi Souri,
I checked the issue and I can confirm that something is happening with the copied data, and monetdb does not like it. This error occurs during the first copy into.
The error I get is server5: /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306: strPut: Assertion `(v[i] & 0x80) == 0' failed.
while trying to load the data. And the trace reads
#4 0x00007ffff72d4c8f in strPut (h=0x7fffbc14d640, dst=0x7fffd4aa3c80, v=0x7fffd4aa3dd0 "Leftover data '*data i am not sure i should share...(?)* "...) at /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306
So I suspect to be a parse error that is not treated as it is supposed to.
This indicates that there is a non-UTF-8 character in the input. Of course, there should not be an assertion error if wrong input is given, so that problem has been fixed in changeset c5460cc0b66b. What then remains is the bad input.
Can we use the main_schema, data, and queries you send me to open a bug report? or is it sensitive data? If we can use them, then I suggest you open a bug report for the correct person to see it and fix it.

Hello Team,
I had shared all the data with Lefteris. When database crashes we restore it from the backup.

Dear Souri,
as both Hannes and Lefteris already mentioned with their replies to your earlier messages, we need detailed instructions (and data) how to reproduce the problem, otherwise, we have no means to debug it.
We easily operate tables with thousands of columns and millions of rows in MonetDB; hence, neither is expected to be a problem in general.
If your server crashes, and then fails to restart, this should be reflected in the merovingian.log . Please re-consult the log and feel free to share the relevant snippets.
If the server fails to restart and you fail to reconnect, how could you test with inserting fewer records into the very same table or inserting all records into a new empty table?
Best, Stefan

Hello, We have a main table with 126 columns and approx. 94000 rows. We are trying to load approx 2500 records from temporary table into main table using query “insert into select” query. The database crashes upon query execution. We get error “ monetdbd: internal error while starting mserver, please refer to the logs ” when to try to connect again.
No specific error is created in log file. 1500 records successfully loads from temp table to main table. We also created another main table with same DDL, that table is empty & inserted all the records from temp successfully without any issue.
What could be the reason? Is 126 cols an issue? Please help. We
are stuck.
(btw: We have machine about 200GB of hard disk & 16 GB RAM (14 GB free))
OS - Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-55-generic x86_64)
