Hi Jon,
I ran connectathon test -N100 and get this crash on the server. Both
server/client are RHEL 5.2 x64 with connectX HCAs
Should I open a bug# on bugzilla?
If you hit a bug, you should open one in bugzilla so it can be tracked.
OK - I just open bug #1571
Do you see the same behavior on mainline or is this isolated to the
RHEL5.2 backport?
I run server on mainline kernel 2.6.27. The server fail at same place;
however, it does not crash
