> Given that segfaults almost never happen in the JVM (I've never seen one)
I've seen 5 segfaults over the last week in our system. Unfortunately we don't enable core dump in our system (yet) so we haven't really had a good sense of what might cause the system. We've been seeing about 30 SIGSEV's over the last three months, but we haven't been able to root cause it yet.
How many jvm:s are you running and what version?
There have been 116 updates since then (33 public). Given that segfaults almost never happen in the JVM (I've never seen one) I can imagine it would be the highest priority to be fixed.
