Hi,
Lately I've seen a few examples of users hitting the vsz_limit (usually trying to "delete" mails i Spam/Junk by moving them to Trash with a large dovecot.index.cache - which resulted in mails left/leaked in the tmp directory of Trash.
Sometimes it seems the client gets into a state were it repeatedly tried to sync the client and server state so it does it again and again, building up the number of files/links in tmp.
It seems the default 1 week interval to "unlink_old_files()" is not enough to prevent this from blowing up inode wise.
However, ... lowering it, - or increasing vsz_limit feels a bit like kicking the can down the road.
PS: This on dovecot 2.2.36
