[OpenSIPS-Users] Memory Leak

[Ben Newlin]

Razvan,

I think you are referring to this commit [1]?

I can see that this was committed 27 days ago, but when I pull the latest 2.3 branch, the change from this commit is not there. It would appear a subsequent commit has removed this change.

The memory leak still exists on the latest 2.3 branch.

Thanks,
Ben Newlin

    Hi, Ben!
    
    This has actually been solved in the latest 2.3 code a few weeks back, 
    but the fix did not "catch" the 2.3.3 release. So if you can, pull the 
    latest 2.3 sources and test again.
    
    Best regards,
    Răzvan
