Hi,
I have been running a 3.4.5 board for about 10 years now and I just ran into a big issue. Im on a shared hosting and all of the sudden I started to get this on my cpanel terminal:
bash: fork: retry: No child processes
following a huge load time every time I tried to browse my board. Then the server just crashed and my host told me my site was causing them a big server overload and that they would need to suspend my account. My board came back after a while but not for long, it went to overload again. My host found that index.php appears to be the problem, so I renamed it and placed an empty index.php instead. The overload goes almost right away, but as soon as I rename it back I start to get the errors on the terminal no matter the time, even when there is nobody supposed to be visiting which leads me to assume its an automated attack directed at index.php but with some sort of query that is overloading the server. Maybe an exploit or something?
Is there anything I can do to fix this issue?
Thank you.
