User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12 i686)
Description of problem:
Redhat 7.1 with kernel 2.4.3-12 would crash after 4 or 5 days of running
applications with large memory. If we run a C program that consumes over
250MB of memory, we would lose X display after a few days. Logging out of
the desktop would then crash the machine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run a large memory program. One that would cause the system to use more
than 1/2 its swap space
2. After a week of continuously running the program, the desktop will no
longer work, i.e. the desktop buttons won't be able to start new
applications. X display is lost.
3. Logout and the computer will crash.
Try upgrading to the current erratum kernel+XFree86. Does this fix
