Re: Re: Re: mserver5 stability problems in acting with multithreaded clients
To: sjoerd@monetdb.org I build Jul2015 branch and tested with my test app and mserver5 errors disappeared :) Nice But, still have problem with Mapi library, where first 1-4 connections get lost, because WSAStartup error. Then I added changes to my test program, and when program starts it preconfigures Windows Sockets, then starts client thread. Now it works: https://gist.github.com/shmutalov/3894fdd22ec62334fe17 Regards, Sherzod Mutalov

Probably a race condition in the code calling WSAStartup. Looking at it, it is clear that the initialization function needs to be called when there is only still a single thread. At the start of your program call the function mnstr_init(); You may need to include stream.h before mapi.h to be able to call this.
