# cat /proc/cpuinfo
# uname -a
Perhaps related, we have a system which uses qlogic FC HBAs to a CX600. Locally it works fine, over NFS using SMP the system crashes (multiple crash dumps uploaded see Service Request 366184). We found UP resolved the oops issue. Current crash dump and logs are included in that service request. This is with all kernels up to and including latest errata. For the longest time it was that the server would only hang but latest SMP kernels actually oops and produce a netdump. Could this be related? https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=138182 Created attachment 110124 [details] Revertion of Sillydelete patch Yes, it appears rpciod is hanging in the same places as in bz# 138182. Please try the attached, which should elimnate the hang. Two days, no hangs... looks good so far Cool... thanks for the update! Created attachment 113735 [details]
perl script & C++ combo to hang nfs, plus systrace
We have several rooms full of Dell Optiplex GX260's running RHEL3. I grabbed
the latest kernel (2.4.21-27.0.4.ELsmp #1 SMP) and I can get nfs to hang
reliably by compiling the attached C++ and using the attached perl script to
run the C++ binary. I've also attached a systrace of the hung machine. Steve
Dickson's attachment above (id=110124) seems to fix the problem but I sort of
expected the patch to have been incorporated into this release.
An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2005-294.html Please see bug 138182 comment #47 for more details. *** This bug has been marked as a duplicate of 138182 *** |
