h2o: (h2o), uid 80: exited on signal 6

Just a question: I sometimes get a lot of these in the kernel log messages on FreeBSD and HardenedBSD systesm running h2o.

pid 56341 (h2o), uid 80: exited on signal 6

Is this to be expected? Why does it exit so often?

Note, there is nothing to be found in the h2o error log and neither in the php-fpm.log.

I have not seen these exits anymore in the last three weeks. Therefore I close this issue.

I believe it is due to some clean-up in the PHP-App (an old TYPO3 installation we inherrited). It is unfortunate that I was not able to pinpoint the cause, but I am 99% sure they had to do with frequent PHP errors and sometimes timeouts we are seeing.

Thanks for trying to help. The backtrace was a very good start.

Thanks to @i110 and @dch for the kind offer. I was too busy and partly away from the office in recent weeks: I think it might be easier to configure a VPS myself because you probably won’t be able to trigger the exit without the actual application (a TYPO3 installation). So I will have to copy over most of the production site, set up the database etc.

BTW, the problem shows up a lot(!) less and I do not know whether this is because of less traffic over the Christmas break and/or some other changes I did to the server.

I will keep you uptodate as soon as I have something to report again.
