Yes its NFSv3 mounts. Thanks Soumya for confirming.

Are you using NFSv3 mount?
I have observed the following errors in ganesha.log:

I was searching in the ganesha community for any similar issues and found these:
https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzill...
which is fixed by Frank in :
https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview....
This patch is not in present in our repo yet and I was thinking of cherry-picking this
change into our FSAL_VFS which is causing the issue.
Frank/Soumya,
Can you confirm if this fix is going to resolve this issue and if I cherry pick this
alone or is there other changes required to resolve this issue please?
yes. AFAIK this alone should most likely fix issue with open_fd_count
going negative.
Thanks,
Soumya
