It appears the I/O is not timing out. Are there any errors on the console leading up to this hang? Is there any multipath code in the stack? Is the kernel tainted? (If so, can you reproduce this on a non-tainted kernel?) Please provide an sosreport for a system where this problem occurs. Based on that, and the answers to the questions above, we will decide whether we need the crash dump. This issue was later raised through REDHAT support channel: https://access.redhat.com/support/cases/00694718 Currently issue was resolved with patches provided by redhat support. We are waiting for input on in which release fix patches would be available.. Please upload the crash dump mentioned in the problem description, along with /var/log/messages file. Will try to pick some info out of the dump. In case required, crash dumps and logs have been uploaded through support case raised with redhat: https://access.redhat.com/support/cases/00694718 We have been notified on that that fix for this problem has been release in RHEL-6.3 GA update. We have not yet been put up resources to verify same. We are working on that. Please reply whether this problem still exists in RHEL6.3 and/or RHEL6.4. We are seing the same issue on RHEL5.8 also. Awaiting response to comment # 8 regarding whether this is still an issue in RHEL6.3 and/or RHEL6.4, because of what was reported in comment # 7. Closing this bug due to lack of response from the reporter. Re-open it if this is still an issue. |
