Created attachment 359778 [details] Backported patch from bug #487700 Tested and confirmed to fix the problem by the customer. We're seeing this bug as well on RHEL 4.8 with procps-3.2.3-8.17, and the reproducer from Bug 487700 works for us as well (and it didn't work the first few times, so if it's not working for you just keep trying it). So please do include the fix in RHEL4's procps. Bug 487700 comment 6 has a reproducer for this.
