It's quite werid that the ACL deny will cause the switch reload.

Any log indicate the msg cause the switch reload?

probably you can find any clue from show tech e.g. crashfile, crash process, reload reason

I would agree with Dazhi that it would be really strange that the ACL logging would have caused the switch to reload. We would need to check for either a crashinfo or looking at the complete logs from the syslog (if configured) would help identifying the root cause. If there is nothing in the logs except these messages & switch didn't crash, let us know. We can look for a known bug.

Regards,

Amit
