Upgraded PHP 5.6 to 7.0 and this happens

[Steini87]

Hey guys,

So I decided it was time to get wit the times and upgrade our server PHP from 5.6 to 7.0 and MySQL from 5.5 to 5.7, it all went without a hitch. Nginx is 1.8 so the stats are

System:
Nginx 1.8
PHP-FPM 7.0
MySQL 5.7

Then it started happening, I realized that the issue ONLY happens on the supporttickets.php file, and nowhere else on the site, no other site reproduces this fault. Below are more indetail as I can get to this and since its ioncube encoded there is not much more information.

2017/10/29 10:45:39 [error] 21391#0: *144046 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 117.240.93.242, server: secure.x.com, request: "GET /x-admin/supporttickets.php?filter=1 HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "secure.x.com"

The moment I had checked and found this in the error, log in the NGINX log file I went on to check what happened at 10:45:39 in PHP-FPM

[29-Oct-2017 10:45:39] WARNING: [pool www] child 3128 exited on signal 11 (SIGSEGV) after 1694.187287 seconds from start

Now that I knew it was SIGSEV which means it faulted, after 1700 seconds nearly, I ran 3128 against the dmesg for just a little more information

php-fpm[3318]: segfault at 7f8736400001 ip 00000000005be969 sp 00007fff727256d0 error 4 in php-fpm[400000+344000]

Even this, this didn't tell me much so i made a core dump, and read it and this was the outcome with few debuginfo's missing but I am no expert on core reading so this is what it pushed out when the error happened

 

Core was generated by `php-fpm: pool www '.

There is nothing more I hav on this, I did open a ticket to WHMCS but in case any of you know why this is happening on PHP 7.0 I would be very appreciative, it's PHP 7.0.24 from Webtatic repo. php70w

None of which stand out to cause this, What frightens me is that this just happened after the upgrade of PHP version, and only on the supporttickets.php page nothing else, no other page reproduces this seen here

all of these are received within the supporttickets.php, nothing else no matter how long the log goes it's not happening on any other page and I don't feel 7.0 down to 5.6 be the solution here.

Also I am running WHMCS 7.3 latest

Downgraded from PHP 7 to PHP 5.6, luckily i kept the htdocs folder backed up as htdocs.56 in case i had to. the 502 is gone on supporttickets.php in the admin area, Something about php70w causes this 1 file to flake on me with PHP-FPM.
