Openfire 3.7.0 gooing OoM every 3 weeks


we are using OpenFire with about 100 users. ActiveDirectory connected. Everything worked well … until we upgraded to 3.7.0.

The Heap fills constantly and GC is not able to clear the heap. So it takes about 3 weeks until openfire goes out of memory.

Is this a known issue? Any hints?

Thank you and regards,
