Running Eclipse or compilers or any application that sets file locks in a view causes Linux Kernel Panic

Troubleshooting


Problem

This technote explains why attempts to run any application that sets file locks in a version 2003.06.00 IBM Rational ClearCase view and VOB context causes Red Hat® Linux® with kernel 2.6.9-42 to panic.

Symptom

While running on Red Hat Enterprise Linux 4 (RHEL4) on kernel 2.6.9-22 and -34 applications that sets file locks in a VOB/View context worked as expected. After upgrading to 2.6.9-42 these same applications caused a kernel panic.

The following are examples of the output from a resulting crash:
