Hello All,

Has anyone seen this strange behavior before?

ASIC engineers are noticing files are corrupt and killing their "jobs".
I did open a ticket with Red Hat and planning to add 8Gb of memory (2gb Currently installed) to the hw-server.
a Kernel upgrade is planned too.

Thanks

After updating the kernel, it didn't solve the issue.

Every time I run md5sum, the checksums change

fsck found no errors on the drive.

Resolved.

There was a misconfiguration on our switch causing these issues.
