[SR-Users] kamailio 4.4.1 DROUTING module memory leak ?

[Uri Shacked]

Ok,
Installed on production at midnight.
After 7 hours with very small traffic the ac_get_maxval keeps on growing.
At startup count = 6 size = 120 bytes
After 7 hours with no more than 1000 calls, cout = 3756 size = 124144.

I have a feeling is still leaks.
