[OpenSIPS-Users] pkmem free_size larger than total_size

[Răzvan Crainea]

Hi, Jeff!

There were some fixes relate to the memory statistics in revision #9322. 
Anyway, the problem was that the statistics were not reported properly, 
but the internal behavior was working as it should. Therefore, your 
OpenSIPS did run out of memory. Try to update your sources and then let 
us know if you still have these issues.

Best regards,
