No one can solve this 503 error :(

[Nikola]

Hey guys

I'm administrating a web shop site which I took over from previous admin.

The issue I'm facing here is that site is giving 503 error page, saying that server cannot handle requests due to the high request volume.

Looking in the logs from DirectAdmin control panel I found that some Litespeed plugin processes are trying to establish connection somewhere probably to litespeed database or their server or something.

Fact #1 Litespeed cash is not even installed (I assume it was installed previously and was uninstalled but some code remained somewhere and is now making troubles)
Fact #2 Lastly I have installed Litespeed cash plugin in desperate hope that it will overrun old remained settings and file, but without much luck, so plugins is now present.
Fact #3 Web server is Litespeed, so this may be some log showing webserver activity

Can anyone help me resolve this or at least how to kill those processes or scripts that are trying to make those connections which are choking access to site?

Or at least if anyone has some idea what can be done to remediate this

Are you using OpenLitespeed or Litespeed?

I don't use litespeed but I found the same issue on this site:

I don't know if you changed php or changed from apache to litespeed.

This can be website dependend, so if nobody answeres here and this does not help you either, you might best ask a web developper or ask over at the litespeed support forums.
