Setting this to "high" won't help much :-) Was this error reported to the ext4 mailing list? What happened before this error? Was the system under load? Can you reproduce this crash? With a current kernel?
This is a Red Hat Enterprise Linux kernel. As such, bugs should be reported to Red Hat and Red Hat has the responsibility for fixing them. If you have a reliable repro on a modern kernel (as opposed to a distribution kernel customized to within an inch of its life and released six years ago), please feel free to open a bug with the information on how to reproduce this on a modern kernel.
Dear，the system under load.I can't to reproduce this problem. Thank you for your help!
(In reply to xierui1010 from comment #3) > Dear，the system under load.I can't to reproduce this problem. > Thank you for your help! Hi xierui I wonder whether you are using emulex be2net network driver. And I got the similar call trace with you. Need to collect some common symptoms for the memory corruption
