Our application freexes occasionally. We used Jstack and have seen the deadlock below. It seems to be very simillar to RF12013, but the stack is slightly different
Found one Java-level deadlock:
=============================
"localhost-startStop-2":
waiting to lock monitor 0x000000000782a368 (object 0x000000078da957e0, a org.richfaces.application.push.impl.SessionImpl),
which is held by "http-nio-30085-exec-4"
"http-nio-30085-exec-4":
waiting to lock monitor 0x00000000085cbe00 (object 0x000000078e8ecf90, a org.atmosphere.cpr.AtmosphereResourceImpl),
which is held by "Atmosphere-AsyncWrite-0"
