Customer seeing a crash while running BEA Weblogic in "-client" with new/latest baseline 1.3.1_02_VERIZON-001. This core dump happened twice, one on Dec 18th, the second on Dec 19th.

The symptons are the same -- none of the app servers stopped running or being
restarted as I checked through all log files.
Also included are the logs for a server hanging that was taken place on
Dec 20th. We are running the alternative thread library as suggested together
with -client option on the New Baseline 1.3.1_02_VERIZON-001. This thread
missing is not related to the core file.
