Various error messages

[Etienne Goyer]

Hello all,

I have upgraded a Murder of 5 boxes, ~80K accounts from 2.1.16 to 2.2.6 
this week-end.  I was used to some error messages as warning ("unable to 
set file descriptor to 1024", etc), but now I have new one to worry 
about.  I would like to know if they are symptomatic of a problem, and 
if yes where I should start looking.

First :

Jun 21 14:10:11 frontend1 imaps[31561]: accepted connection
Jun 21 14:10:11 frontend1 imaps[31561]: starttls: TLSv1 with cipher 
RC4-MD5 (128/128 bits reused) no authentication
Jun 21 14:10:11 frontend1 imaps[31561]: login: somehost.somewhere 
[1.2.3.4] someusername plaintext+TLS
Jun 21 14:10:11 frontend1 imaps[31561]: open: user someusername opened 
INBOX on backend2
Jun 21 14:10:11 frontend1 imaps[31561]: PROTERR: end of file reached

Annoyingly, I can't succeed to reproduce this when I connect using 
Mozilla Mail.  So far, I have not heard about any user complaining thus 
I can't tell which MUA provoke this error (or even if it is MUA-related).

Another error I have regularly in my log is :

Jun 21 14:26:54 frontend1 master[12195]: process 2270 exited, status 75
Jun 21 14:26:54 frontend1 master[12195]: service pop3s pid 2270 in BUSY 
state: terminated abnormally

This happen with both pop3s and imaps.

I know just pasting from the log is not enough to pinpoint the exact 
problems, but I would appreciate to know if they harmless messages or if 
I should try to investigate the source.

Thanks all for your insight !
