Description Josh Bressers 2004-09-21 14:41:43 UTC 
It is possible for a user to exhaust the system process table by
causing a large number of threads/processes to be left in a zombie state.

Comment 1 Jim Paradis 2005-02-09 02:10:17 UTC 
See Bug 133069.  The fix referenced above does not address the issue under
discussion here.  The fix referenced in 133069 cannot be directly ported to RHEL
due to kabi, but there's a proposal to implement something similar that will work.

Jim - Update with status for U7.
Comment 3 Mark J. Cox 2005-06-03 11:41:33 UTC
