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
