php-fpm segfault
« on: January 11, 2021, 09:52:04 PM »
I've recently started having php-fpm (for php-fpm73) start segfaulting :

Jan 11 21:11:41 kern info kernel php-fpm[1397]: segfault at 104 ip 0000000000957c52 sp 00007ffd3b6526c0 error 4 in php-fpm[400000+da8000]
Jan 11 21:11:41 daemon notice systemd php-fpm73.service: main process exited, code=killed, status=11/SEGV
Jan 11 21:11:41 daemon notice systemd Unit php-fpm73.service entered failed state.
Jan 11 21:11:41 daemon warning systemd php-fpm73.service failed.

I was thinking that maybe I had done something that rebuilt php-fpm but as you can see, all the datestamps are old :

[root@web3 conf]# ls -lart /opt/alt/php-fpm73/usr/sbin/

drwxr-xr-x 3 root root  4096 Jan 11 16:10 ..

Even my users configs are a couple months old.
running cwp pro on centos 7
all recent updates except for a mysql update

I did change the DNS on one site recently to make it live off my VPS but these are all fairly small websites with little traffic.

monit appears to be restarting things for now, but I would like to track this down if anyone can assist.

Shared hosting is cheap, these days.  :-X

I rebuilt php 7.3  - it was originally showing php 7.3.0 - rebuilt to the latest 7.3.26 I believe.

I have not had a single crash since
