I have Exim servers remote logging via Syslog. In the past I've never noticed this issue until recently after we upgraded to 4.85. Could just be a coincidence...
Randomly we miss log messages from Exim for "Start queue run". We always get the "End queue run". A tcpdump on the server itself shows these "Start queue run" messages/packets never even gets generated via syslog. Now normally I would think that random missing messages would be a network issue, but since it happens on the server itself (before it goes on the wire) and that it's only "Start queue run" messages; it seems like a bug??
ie:
grep "queue run" *
Feb 4 00:09:32.763 hostname exim[63875]: Start queue run: pid=63875
Feb 4 00:09:32.764 hostname exim[63875]: End queue run: pid=63875
Feb 4 00:19:32.791 hostname exim[64236]: End queue run: pid=64236
Feb 4 00:29:32.809 hostname exim[64581]: Start queue run: pid=64581
Feb 4 00:29:32.810 hostname exim[64581]: End queue run: pid=64581
Feb 4 00:39:32.814 hostname exim[64933]: Start queue run: pid=64933
Feb 4 00:39:32.814 hostname exim[64933]: End queue run: pid=64933
Feb 4 00:49:32.821 hostname exim[65285]: Start queue run: pid=65285
Feb 4 00:49:32.821 hostname exim[65285]: End queue run: pid=65285
Feb 4 00:59:32.833 hostname exim[65634]: End queue run: pid=65634
Feb 4 01:09:32.853 hostname exim[65988]: Start queue run: pid=65988
Feb 4 01:09:32.854 hostname exim[65988]: End queue run: pid=65988
Feb 4 01:19:32.866 hostname exim[66341]: End queue run: pid=66341
Feb 4 01:29:32.879 hostname exim[66711]: Start queue run: pid=66711
Feb 4 01:29:32.880 hostname exim[66711]: End queue run: pid=66711
Feb 4 01:39:32.933 hostname exim[67056]: End queue run: pid=67056
Feb 4 01:49:32.987 hostname exim[67413]: Start queue run: pid=67413
Feb 4 01:49:32.987 hostname exim[67413]: End queue run: pid=67413
Feb 4 01:59:32.992 hostname exim[67762]: End queue run: pid=67762
Basic logging config:
syslog_duplication = false
syslog_timestamp = false
log_file_path = syslog
OS: FreeBSD 10.1
Ideas?
