Hi Matt, One of our network experts thinks it could be packet loss or packet reordering. They are looking at your trace. I will update the bugzilla when I know more. the server and storage unit are connected on the same switch - there's nothing to indicate that the switch is losing any packets (it works fine with the equalogic unit connected on it too) - there's no bad "counters" on any of the ports. That is what the network people said too. Here is what they said about the wireshark trace: OK, what wireshark indicated wasn't lost segment as seen by the receiver, but a segment that was lost on the way to wireshark. This bug/component is not included in scope for RHEL-5.11.0 which is the last RHEL5 minor release. This Bugzilla will soon be CLOSED as WONTFIX (at the end of RHEL5.11 development phase (Apr 22, 2014)). Please contact your account manager or support representative in case you need to escalate this bug. Thank you for submitting this request for inclusion in Red Hat Enterprise Linux 5. We've carefully evaluated the request, but are unable to include it in RHEL5 stream. If the issue is critical for your business, please provide additional business justification through the appropriate support channels (https://access.redhat.com/site/support). |
