Reproducible - Daily cores dumps in pre-production system.

Targeted release: 1.3.1_02


======================================================================

###@###.### 2001-11-09

What customer have included in the C stack trace up to the <<snip>> is the dbx
output for the current thread where the failure occurred. Additionally,
after the <<snip>> we have included the thread information for gc. One of
the things being queried by our engineer is the line near the top of the
trace 'dbx: warning: Frame::refresh(): signal handler has no sigcontext',
which is not normally seen.

Let me know whatever other information is required. If your engineer needs
to speak to IBM's, then I'm sure we can arrange that.

======================================================================
###@###.### 2001-11-13

Added 7 attachments containing dbxtrace.out, activity.log, stderr.log,
stdout.log, and source code used to replicate core dump.

See Escalation for Details (or Comments).
