Description
Sometimes after rebooting syslogd shows that it has crashed. Rebooting usually fixes the issue. Here is what I see in the system logs.
Feb 8 20:46:25 syslogd: exiting on signal 15
Feb 8 20:46:25 kernel: done.
I have pfsense to only log locally.

This typically happens when you have a corrupted log file. The first attempted write to said log file will crash syslogd. Reset the log files from Status > System Logs, Settings tab.
That said, we probably need to come up with a way to detect broken/corrupted log files, assuming your problem is from that same cause.

It looks like this fixed my issue. I had the log size set to 8192 thinking that it was in KB and realized that the field is in bytes so I was setting it to 8K when the default shows 500KB. Im guessing that it was corrupting because the log file was to small and unable to rollover right after boot is complete.

I set the log file size low and ran some tests and still couldn't make it crash.
If someone else finds syslogd crashing similar, please tar up the contents of /var/log/ before resetting the logs. If resetting the logs fixes the problem again, make arrangements to get the archive/backup of the logs to us, either attached on the ticket or privately.

I just had this happen again after rebooting my box from Bug #4392. How can I email you the logs?
Updated by Jim Pingle over 9 years ago
If you have made an archive of the logs you can post them on a site like Google Drive or Dropbox and PM me the URL on the forum or send it to me directly, though it may be too large to e-mail. Address is jimp (at) pfsense [dot] org.

I sent you an email yesterday with the logs (9MB). Did you get the email?
Updated by Jim Pingle over 9 years ago
I received it, but it may be Tuesday before I have a chance to look at the logs.

I still can't seem to reproduce it here even with a "bad" set of logs and similar settings. There must be some other contributing factor at work.
I'm curious if lighttpd will produce any errors if/when syslogd breaks when saving the syslog settings. To enable some extra logging in lighttpd, apply this patch:
http://files.atx.pfsense.org/jimp/patches/lighttpd-breakage-log.diff (don't apply that now, see Chris' later message)
And then from the console, use option 11 to restart lighttpd. Try clicking Save on Status > System Logs, Settings tab and then if syslogd is not running, check /var/log/lighttpd-breakage.log to see if anything shows up there.

every circumstance I could replicate is fixed by what I just pushed.

I applied the patch and it created the lighttpd-breakage.log but its 0bytes. After applying the patch and restarting ligttpd here is what was logged in system log.

I havent seen this bug crop up on my other 2 systems so I'm beginning to wonder if its just something very specific to this machine. My other 2 systems were on 2.1.5 had inplace upgrades to 2.2-RELEASE. The system that is having this issue was a new install on 2.2RC (not sure what daily snapshot) and upgraded through the daily snapshots to 2.2-RELEASE. I thinking I should try rebuilding this machine from the 2.2-RELEASE and see if that solves the issue. All 3 systems have the same base hardware, however this box also has a Broadcom accelerator card (cryptodev) and and Atheros AR9380 wireless card (AP mode).

No need for that patch I posted now, Chris found the actual fix after that. The fix is in the commits shown in the "Associated revisions" section here on the ticket.

- Subject changed from syslogd crashing after reboot to syslogd stops and fails to restart during boot in some cases
anyone who's having issues with syslogd not running, install the System Patches package, then browse to System>Patches, and add a new patch. Give it a description as desired, put in commit ID cfda8861b93ef0a2daf2cc9ca2424200e45dd84f, and leave all else at defaults. Save. Then hit Fetch, and Apply. This fix will then be in place.

It does not, this has been fixed since 2.2.1. Your log clearly shows it's starting again. Post to the forum with more info on what you're trying to do.

Hi Chris Thank you for the reply when you say it clearly shows its starting again but why the syslogd: exiting on signal 15 im running ELK which pfSense sends all the logs and for some reason wont work i posted on the forums but no luck so far :(
