Centos 6.3 and dovecot with an abrt problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Everyone,

I have a mail server  running CentOS release 6.3 (Final) with
2.6.32-279.22.1.el6.i686 kernel that is reporting errors to me
pertaining dovecot.  I have appended the error message to this note.
There is only one user that appears to generate this message, and it is
generated to me by way of e-mail without a perceptible problem to the
user which is not me.  

This particular user had an inbox greater than 2 gigs in size, so I
asked him to move or delete unwanted files, which reduced the size of
the inbox to 400 megs.  Unfortunately, the abrt messages have
continued.  

I did a google search on  : "usr/libexec/dovecot/imap was killed by
signal 6", but did not find much that I could use to help me debug this.
Can any of you point me in the right direction.
'
Thanks much!!!

Greg
