Postfix error regarding smtp_scache.db

Operating system Ubuntu Linux 18.04.6
Webmin version 2.021
Usermin version 1.861
Virtualmin version 7.7 Pro

I see the following error in syslog.

postfix/tlsmgr[1930]: warning: btree:/var/lib/postfix/smtp_scache is unavailable. open database /var/lib/postfix/smtp_scache.db: No space left on device

I have plenty of space on all drives. This might be a quota issue of some kind. Can I adjust the disk space quota for smtp_scache.db within Webmin?

Do you really have enough disk space? Past here output from df -h command.

Quotas don’t apply to the Postfix user in a Virtualmin system, and I don’t think smtp_scache.db is ever interacted with directly by users, so I don’t think it can be quotas, unless you’ve imposed quotas on Postfix yourself.

So, yes, you can adjust quotas in Webmin, but you shouldn’t have quotas imposed on the Postfix user to start with.
