[MonetDB-users] Mapi connection hangs
Hi,
I reached a certain state where there's some sort of data corruption that prevents MonetDB to start. I get this message: !ERROR: Please move away <log folder> and its corresponding dbfarm. !mvc_init: unable to create system tables.
I use Mapi to connect to Monet, but the problem is that in this case I do net get back a failed mapi connection - instead the connection attempt hangs and never returns. Is this a mapi bug?
If I remove the log folder Monet goes back up again.
I am using v2.28.5 compiled on Windows from CVS (branch May2009).

I think this is a bug indeed. The error probably only appears after the first connect attempt?
I'm not exactly sure what you mean. While the mapi connetion hangs, If I open parallel mapi connections, they cannot connect too. Restarting the server without having cleared the log folder still results in hanging mapi connection attempts.

Thou salt never destroy a MonetDB database log directory or clear it !!!
The system will do so if it is safe and all pending updates have been applied correctly.
