what kernel version are you using EXACTLY ? also can you get sysreq-T output during the hang ? Created attachment 89069 [details]
dmesg from kernel on hung ps
dmesg from kernel after ps command hangs...
Created attachment 89070 [details]
partial output from 'strace ps' after ps command hangs
uname -a gives: Linux philpott.houston.ibm.com 2.4.18-18.7.xcustom #2 Mon Dec 9 14:08:47 CST 2002 i686 unknown How do I get sysreq-T output exactly? The xcustom is the stock 2.4.18-18.7.x kernel with NTFS support compiled as a module. never mind the sysreq-t output; you got an oops not a deadlock can you paste the output of lsmod ?

I have 1 GB of RAM. I added a 1 GB swapfile and everything seems OK. Please close this bug. I'm currently seeing this bug on a a system running 2.4.20-20.7bigmem. I don't think it's related to the size of the swap: penguinC:~$ free total used free shared buffers cached Mem: 2062708 1860252 202456 0 7548 1661956 -/+ buffers/cache: 190748 1871960 Swap: 2080312 30252 2050060 penguinC:~$ uname -a Linux penguinC.corp.fiveprime.net 2.4.20-20.7bigmem #1 SMP Mon Aug 18 14:34:37 EDT 2003 i686 unknown my strace output looks the same; it dies in the middle of a read, leaving "read(7," as the last line. Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
