Hello,
We got the following error messages on our 1.4.9 Lustre clients. Our
Lustre servers are also running 1.4.9.
The first two incidents happened at the same instance where both clients
were busy running two IOR jobs per each. The last incident happened when
the client was not running any jobs and was idle.
These errors did not create any other bug/logs on clients.
We are not at this point sure if this is a Lustre problem or something
else, but the RIP line ({:ksocklnd:ksocknal_process_transmit+969}) makes
us think it might be a Lustre problem.
Has anyone seen something like this?

PS: The same hardware was running without any problems before these
errors and after a reboot, they are still running fine and no hardware
configuration changes have been made on these clients.
Thanks,
