I often get a lot of 500 errors when trying to load my PHP pages (approx. 8-10PM PST). Then I have to wait a few minutes before refreshing the page or it gives me the error again. So some limit must be being reached. But the server load has been weird. Before the power failure, Stevie's server load usually stayed around 2-3 or would jump up to 14+. Now it usually hangs around 6.
well i get this issue too but there is no time related about it .
i think that there is a limit on connections per site , so if you upload some files to your public_html
the numbers of connection is raised up .
i am getting this 500 error also . i don't know how to fix it maybe staff members will help about this issue.
to the issue related server load as shown on monitors its really weird but i don't know how its calculate it .
main issue is that might be some background process like cron or some other job that take all power to him self or hardware related problem.
the corrective disk supposed to be at list 24 hours but it has done in 2.5 hours & no errors found so i believe that it didn't evan worked right .
some error must be found cuz the power failure shut down the server on spot & no close file had been generated .
when you start the server after power failure it need to show you some log about missing file or message about power failure or shut down unsuspected
maybe in this log you got your answer to the issue .
