php-fpm: several "exited on signal 11 (SIGSEGV)"


Recommended Posts

This may be a dumb question...but, my server has multiple versions of PHP, and I only noticed this issue when I changed my cron line to include the PHP 7.3 path. Can't I just run the cron job using the PHP 7.2 path and keep running my site on PHP 7.3? To me it appears that this error appears to be triggered by the cron job.

To clarify, if I run the cron using this path:

/opt/cpanel/ea-php72/root/usr/bin/php

I see no errors...but if I run it using this one:

/opt/cpanel/ea-php73/root/usr/bin/php

I do see the errors.

I understand, and am running PHP 7.3 without the patch, and without the errors. My point was that I believe the errors are caused by the cron script, which I continue to run under PHP 7.2. With this setup I do not see the errors reported in this thread.

I tried disabled cron for an hour to figure out .. but i still noticed the error. Can someone please try what's suggested above? I hope it work for someone besides sadams101 and then may be i will just re-install php 7.3 and 7.2 again.

The proper solution is to use the patch or wait around a week for the new version that will include the patch and you will not need to do anything custom...

Update: I am seeing the errors in my logs, so simply running the cron under PHP 7.2 while running the site under 7.3 isn't going to stop this. I do believe that the errors may still be cron-related thought, as I was being emailed errors by the cron job when it ran under PHP 7.3. 

I'll probably just wait for the update and continue running PHP 7.3 though, as the errors are not causing obvious issues with anyone, and there are only 10-20 a day like this:

I've only just found this, I've had the same issue since around when you started the topic. This has been coupled with occasional 503 service unavailable errors ONLY on the home page, after which on the following refresh the recent topics widget has disappeared. It will return a minute later (in admin cp I have sidebar blocks cached to 1 minute).

I gave my host the time it happened last night and this was the error

Working like a charm.

Errors from the previous version have disappeared from the logs 👀

Hoping and waiting for PHP 7.3.7 to become available via WHM/CPanel Yum Update sometime before the next millennium! I went back to 7.3 in anticipation last week and the 503's are driving me nuts again. Why are they so slow?!  😤
