Good day all, I am testing mserver5 with multithreaded client and have stability problems. I wrote a simple app in C#, which uses wrapper around Mapi (pure calls to libmapi.dll functions). The app creates 1000 tasks (threads), each thread opens connection to mserver5, then sends a simple query: "SELECT {0}, NOW();", where "{0}" is thread number, and fetchs the result. Problems are: 1. When my application starts to execute threads, always 1st, 2nd or 3rd connection will be lost, and I can't reconnect from that thread. 2. Sometimes there is error on mserver5, which causes connection lost on the client: "!SABAOTHgetMyStatus: MALException:sabaoth.getmystatus:could not find my own database?!?" mserver5 is running on the local machine, same as client. I tryied to set a gdk_nr_threads option to 1, 8, 16, and get the same problems. I am running on Windows 7 x64, 16GB RAM, Intel i7-5500 CPU Regards, Sherzod Mutalov
