Steps to reproduce

I edited the default sizelimit = 10485760 into config.php to allow a file of 59 MB
I uploaded and sent a MP$ file of 59 MB

What happens

After a short upload time I see an error:

What should happen

The file should be upload successfully with the relative link

Additional information

Server error:
Got error 'PHP message: PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 80355920 bytes) in Unknown on line 0'

Basic information

I prefer not sharing the URL in public

Centos 7

I'm using Apache 2.4, PHP 7.4 and during the upload I checked the CPU and RAM usage and was never at 100 % but much lower.
Consider also on the same server I tried to attach the same file in another PHP app (an help desk app) and the file was attached without errors.

Browser:

Firefox 94.0.1

PrivateBin version:

1.3.5

I can reproduce this issue on https://privatebin.net: Yes / No

No because attachments are not allowed.

Another possible issue is that no alert message alert user if the attachment exceed the max size set in the config file.
Before upload maybe a check should check attachment size and print an error if the size is out of the allowed bytes set in the config file.
