I've been battling these abends for several months and they seem to be getting worse and occurring more often. It was happening back on SP7 and I thought surely that SP8 would fix it. The only thing that we notice that stops working after the abend is GroupWise WebAccess (now version 8 SP1 HP1, started while still on GW 7.0.3). A restart of Apache, Tomcat or the GW WebAccess agent doesn't fix it, only a server restart fixes it. I don't really know if this is a GroupWise issue, though, as none of the abends seem to reference any GW modules. I need another set of eyes to look at this.

The abend log is attached.
