I have been having issues with the system becoming unresponsive when coping files from the cache drive to the array.  This happens most often if I am doing it from the console with MC, although it can happen with SMB copies. Usually, if I wait long enough, things will return to normal and I will end up with some call traces in the log.  Sometimes I have to do a hard reset to get the server back.

 

This has been going on for a little while now and is starting to get annoying.  I have seen a few posts with similar issues (out of memory and call traces when using the Mover, which does essentially the same thing, I believe), but not real root cause was identified.

 

Logs attached.  Any ideas?

New kernel on v6.4 should fix the OOM errors, also there's a new mover, you may want to try it if you don't mind running a beta release.

Thanks for the reply.

 

Beta OSes scare me in principle.  Any idea how far away 6.4 is from general release?
