Hi Soumi, I'll have a look today.
Hi Soumi, You mention that the MG logs were collected when the MDS were online. I'm afraid these logs _might_ not be of much help (I'm unable to log into supportshell right now, so I haven't gone through the logs yet). As Patrick mentioned in his comment, we'd need the MG logs once the MDS hits the OOM failure to accurately diagnose the issue.
Thank you Soumi. Looking into it now...
