Issue Plesk segfault due to error 4 in ioncube_loader_lin_7.4.so

Server operating system version

AlmaLinux 8.10

Plesk version and microupdate number

18.0.65 Update #1

My website (PHP 7.4 FPM Nginx) stopped working on some pages with the following error:

2024-11-20 10:10:39	Error	xx.xx.xx.xx	503	GET /api/products?page=1&limit=24&orderBy%5Bname%5D=asc&gender%5Bin%5D%5B%5D=X-BIONIC%C2%AE+WOMEN&line%5Bin%5D%5B%5D=ENERGIZER&available%5Beq%5D=1&status%5Beq%5D=10&season%5Beq%5D=XTEFW24XB HTTP/1.0			1007	Apache SSL/TLS access

As soon as I request that url, the error shows in /var/log/messages:

Nov 20 10:09:11 juno kernel: php-fpm[3778005]: segfault at 7ff9839393f3 ip 00007ff97e061770 sp 00007ffdb7319138 error 4 in ioncube_loader_lin_7.4.so[7ff97dfab000+145000]

If I disable the iocube extension page works correctly.

What should I do?

Hi,
have you tried to re-install PHP?

 

[ChristophRo]

• let ioncube disabled (if you don't have any encoded/encrypted PHP files, you really do not need this extension anymore)
• try to download latest (precompiled) ioncube extension from here: ionCube Loader - Configure for your website to run protected PHP code and replace the file ioncube_loader_lin_7.4.so in folder /opt/plesk/php/7.4/lib/php/modules/ with that version

 

[Polmonino]

I had to disable the extension, and I don't like it even though I don't use it. I couldn't reinstall the PHP version because it's a production server where I can't create downtime or issues.

You can try to follow Cristoph's suggestion and update just modules file.

So I can confirm manually updating ionCube fixes the issue for my case (an old broken authentification for symfony, causing segfaults and 503 errors).
But ultimately the problem is that the embedded ionCube in Plesk's PHP 7.4 is obsolete... More obsolete than PHP 7.4 itself.
So this should be fixed at package level by Plesk.

The ionCube version shipped with PHP 7.4 is 11.0.1, which as far as I am aware is the correct version corresponding to PHP 7.4. @LRob , please do correct me if I am wrong.

 

[ChristophRo]

latest ionCube release for PHP 7.4 is v14.4.0

 

[Sebahat.hadzhi]

Thanks, @ChristophRo . I will double-check with our team and follow-up with more details.

 

[LRob]

You are both right.
Every ionCube version comes compatible with every single PHP version. And latest at the time of writing is 14.4.0. Link: ionCube Loader - Configure for your website to run protected PHP code

Original file:

getVersion

An update within Plesk packages would be handy and prevent segfaults and weird 503 errors that take hours to diagnose.
(btw, thanks for people making and participating to this post, and putting me on the right track)

Best regards
