503 Service unavailable
« on: March 26, 2024, 06:47:35 PM »
I am encountering this problem and I don't know how to solve it.

I have a PHP script, which in the past worked for me without any problem on the same database, same environment...etc...

But it was on another host and another panel...

I launch it, it works, and from time to time, I get this error message, 503 service unavailable.
If I change a number in the url (what it does is that it imports data from one site to another) it continues without a problem.

After a lot of searching, the only error in the log I see is:
"child 4484 exited on signal 11 (sigsegv) after xxxxx seconds"

I have increased the times (set to -1) resources in php, in php-fpm I have set:
"pm = ondemand
pm.max_children = 100
pm.max_requests = 10000
pm.process_idle_timeout = 900s"
I did get that the max_children was low, it was advisable to raise it, but it was not the error.

I deleted the error log, I repeat the process, and the only error that appears is the previous one, signal 11...

I've been like this for 1 month or more, and I'm desperate...

Any ideas?

Did you check (and increase) max execution time, memory limit, etc. in your php.ini?

Yes, was the first I was try.
In this moment, I have this values:

('memory_limit', '256M')
('upload_max_filesize', '128M');
('post_max_size', '256M');
('max_input_time', '-1');
('max_execution_time', '-1');
('default_socket_timeout', '-1');

And I try with 512M, 256M and 512M (in the order, mem limit, upload max, post max...)
Also I try with 1024M, 512M and 1024M.
Same result all time...

Thanks for your reply.
