Hi guys, So far no luck searching for 8A2993E3003B. :( The system is heavily used. From what I understand this machine relays all mail to our main mx server and we have a lot of email being relayed daily. The strange part is that it works all week up until late Saturday/Sunday in the AM hours.
Here are all log files for mail. I have searched all log files for the specific string but no luck. Performing another search for all warning, error, fatal, panic on all previous log files has given me a bit more info. The following is certain errors I have noticed pop up more often than not: # egrep (warning|error|fatal|panic): /var/log/maillog* | more /var/log/maillog:Dec 11 05:09:19 batch-ca4-02 postfix/cleanup[31691]: warning: timeout on cleanup socket while reading input attribute name /var/log/maillog:Dec 11 05:31:27 batch-ca4-02 postfix/cleanup[31691]: warning: 8A2993E3003B: read timeout on cleanup socket /var/log/maillog:Dec 13 12:04:13 batch-ca4-02 postfix/postdrop[15153]: warning: uid=0: Illegal seek /var/log/maillog:Dec 13 04:04:13 batch-ca4-02 postfix/sendmail[15152]: fatal: root(0): queue file write error /var/log/maillog:Dec 14 12:03:07 batch-ca4-02 postfix/postdrop[12285]: warning: uid=0: Illegal seek /var/log/maillog:Dec 14 04:03:07 batch-ca4-02 postfix/sendmail[12280]: fatal: root(0): queue file write error /var/log/maillog:Dec 15 12:03:07 batch-ca4-02 postfix/postdrop[21744]: warning: uid=0: Illegal seek /var/log/maillog:Dec 15 04:03:07 batch-ca4-02 postfix/sendmail[21739]: fatal: root(0): queue file write error /var/log/maillog.1:Dec 4 05:18:29 batch-ca4-02 postfix/cleanup[6555]: warning: timeout on cleanup socket while reading input attribute name /var/log/maillog.1:Dec 4 05:45:13 batch-ca4-02 postfix/cleanup[6555]: warning: 0433D3E3003A: read timeout on cleanup socket /var/log/maillog:Dec 15 12:03:07 batch-ca4-02 postfix/postdrop[21744]: warning: uid=0: Illegal seek /var/log/maillog:Dec 15 04:03:07 batch-ca4-02 postfix/sendmail[21739]: fatal: root(0): queue file write error /var/log/maillog.1:Dec 5 12:03:47 batch-ca4-02 postfix/postdrop[4667]: warning: uid=0: Illegal seek /var/log/maillog.1:Dec 5 04:03:47 batch-ca4-02 postfix/sendmail[4660]: fatal: root(0): queue file write error (I tried searching for 0433D3E3003A as well but to no avail.) # ls -ld /var/log/maillog* -rw------- 1 root root 194889523 Dec 15 10:48 /var/log/maillog -rw------- 1 root root 370337428 Dec 11 04:04 /var/log/maillog.1 -rw------- 1 root root 644886321 Dec 4 04:03 /var/log/maillog.2 -rw------- 1 root root 250479845 Nov 27 04:03 /var/log/maillog.3 -rw------- 1 root root 11139266 Nov 20 04:02 /var/log/maillog.4 I also commented out fallback relay as it was active but left blank in master.cf. Not sure if that has anything to do with it but better safe than sorry. # When relaying mail as backup MX, disable fallback_relay to avoid MX loops relay unix - - n - - smtp # -o fallback_relay= I'm going to wait and see what happens this weekend and when it happens again I'll try to get more info for you. Thanks again for the help.
