XF 1.2 503 error code caused from a table error

[Tarynjh]

So my site was working perfectly fine until about an hour and a half ago, where I received a 503 error. At this point in time, I was trying to receive help in another thread on here about postbit unevenness, when all of a sudden the site crashes. Since then, I've received five pages full of errors in my server error log pertaining to some table. What table? I have no idea, since I wasn't even touching anything at that point in time. My co-admin has stepped away for the next few days as he's recovering from surgery, so there's no way he was doing anything within the ACP that could've caused it.

This is the error that shows up for 5 pages in a row:

Update:

I am about to die from laughter at the moronic robot tech support team. This guy claimed he just checked my CPU/memory usage and claim it has been exceeded. This is a screenshot taken from about 3 seconds ago, approximately:



Does that LOOK like I've exceeded my usage!??!!

Try to truncate your xf_session table. That should fix the error.

Remember to backup your forum first.

Forgive me for sounding stupid, but how exactly do I do that?

 

[Tarynjh]

Dear Lord, I figured it out. Thank you so much Julian!
