[SR-Users] Memory issue

[Daniel-Constantin Mierla]

Hello,

what version are you using? Are you doing sql queries that return large 
number of records (e.g., via sqlops)? Are you using any custom module 
you developed?

The crash was fixed in master branch, but somehow forgotten to be 
backported -- it is now in branch 4.1.

Cheers,
Daniel
