On tools-mail, there are often errors in exim's paniclog: | root@tools-mail:~# cat /var/log/exim4/paniclog | 2014-10-30 16:29:09 1Xjsaz-0004TE-Hw re-exec of exim (/usr/sbin/exim4) with -Mc failed: No such file or directory | 2014-10-30 21:09:04 1Xjwxs-0002Vi-A9 re-exec of exim (/usr/sbin/exim4) with -Mc failed: No such file or directory | 2014-10-30 23:49:05 1XjzSj-0006Kv-Ej re-exec of exim (/usr/sbin/exim4) with -Mc failed: No such file or directory | 2014-11-01 07:48:50 1XkTQY-00047u-0m re-exec of exim (/usr/sbin/exim4) with -Mc failed: No such file or directory | 2014-11-01 17:50:07 1XkcoR-0007T8-1y re-exec of exim (/usr/sbin/exim4) with -Mc failed: No such file or directory | root@tools-mail:~# These seem to stem from multiple exim queue runners running at the same time: | root@tools-mail:~# ps aux | fgrep exim | 107 1215 0.0 0.0 108852 1600 ?
