One of our dovecot-servers (v2.0.14) got a bit too busy last evening:
Sep 13 20:39:18 popimap1 dovecot: master: Warning: service(pop3-login): process_limit reached, client connections are being dropped
then logged a few:
Sep 13 20:39:20 popimap1 dovecot: pop3(XXXXXXXXX@YYYYY.YY): Warning: I/O leak: 0x3829233d20 (10) Sep 13 20:39:20 popimap1 dovecot: pop3(XXXXXXXXX@YYYYY.YY): Warning: Timeout leak: 0x3829233ce0
Could you show the output of:
gdb /usr/local/libexec/dovecot/pop3 # or whatever path it is in x 0x3829233d20 x 0x3829233ce0
I guess the client isn't being destroyed properly for some reason..
but what has me a bit worried is these:
imap(user@xxx.xxx): Warning: Subscriptions file /path/to/user@xxx.xxx/subscriptions: Removing invalid entry: .Sent imap(user@xxx.xxx): Warning: Subscriptions file /path/to/user@xxx.xxx/subscriptions: Removing invalid entry: .Spam imap(user@xxx.xxx): Warning: Subscriptions file /path/to/user@xxx.xxx/subscriptions: Removing invalid entry: .Drafts imap(user@xxx.xxx): Warning: Subscriptions file /path/to/user@xxx.xxx/subscriptions: Removing invalid entry: .Trash
These are simply broken subscription entries that have never worked. They're not supposed to begin with a ".". In older Dovecot versions they were shown to clients, but I don't know what clients would have done with such broken entries. I guess some could have shown them "correctly", some could have shown them in a broken way and some could have just ignored them.
