Ive been getting a LOT of these errors since 1.1.2:
What version did you use before?
I used 1.1-rc4 -> 1.1.1 -> 1.1.2
So far ive seen this with 1800 customers, and we're getting active complaints about errors in imap clients. When I check the users log I always see this error.. This always happens with COPY commands in Squirrelmail.
*always*? Does the patch here help:
I phrased it wrong. All complaints are exactly the same, but it of course doesnt happen with every COPY, else our customers would be unable to use imap :)
They all paste some squirrelmail error with a dutch message basically saying: connection dropped by imap server: Query: COPY 983,987 "Trash" It's always a COPY command they're pasting.
They often say it took a while to get the error, and some people are suggesting it's only with large emails. So it could be a PHP timeout related bug, although im not positive.
I dont think it's a coincidence that every single person that complaints has that set of errors in the dovecot error log. Over the past week ive found 1800 seperate users, and thats still only a fraction of our total user base.

But even then, errors in cache file handling are ignored and they shouldn't be visible to clients. What error exactly do the clients see? Does the COPY command fail with NO? Does anything else get logged besides these rename/file_dotlock_replace lines?
I dont know exactly what the clients see. It looks like php loses the connection to the imap server. Ive been trying to find a customer that can repeat this consistently so I can turn rawlog on. I dont see any dovecot crashes though.
I'll add that patch to 1 or 2 servers and see if the errors disappear on those servers.
