[SR-Users] Memory Leak on DB Errors?

[Daniel-Constantin Mierla]

Hello,

sqlops is using pkg and tm shm, so they should not be directly related, 
but maybe in the way config file works.

Can you run it again with memlog lower than debug and see where the 
allocated (not-freed) chunks were done? It should appear soon, not 
waiting for out of mem message.

If you haven't restarted, there is a way to attach with gdb and walk 
through shm allocated chunks to spot the occurences.

Cheers,
Daniel
