508 resource limit is reached

  • My account on a very inexpensive web host provider was summarily suspended w/o explanation. When it was reinstated two days later they said (with “ticket”; these guys do not answer or talk on the phone), actually hinted, that i should look at “scripts” for excessive usage, and that there were performance problems on my (shared) server.

    Prior to the suspension, everything worked great for about 6 months since i set up the account — at least from my perspective.

    Adding complication, there are two domains in the same account, each with wordpress. Both generate a trivial amount of “real” traffic; the rest comes from crawlers and, presumably, malicious/hackers.

    After ~ 2 days of suspension my account was reinstated. But at this time wordpress was virtually unusable, i would get 508 Resource Limited every minute or two when i tried to access, and when pages did load they were painfully slow (a minute?). Any static content on the account was fine. Looking at the “visitors” in cPanel, nothing looked out of the ordinary. I mean there was no on-going/obvious ddos attack or whatever.

    I have a hypothesis that my account, after the suspension, was put on some sort of crackdown — is that a thing? Like is there a cPanel (administrator) function to do that, or something?

    I quickly moved that domain to a different web host provider and it’s working fine; very snappy, and not one 508/Resource Limited error.

    One thing I did decide to check was, e.g. back in December, when everything appeared fine to me, i was horrified to find in the awstats top urls that things like wp-login was accessed over 10,000 times!
    “real” content is accessed, at most, a few hundred.
    Could this be tipping me over the edge of 508/Resource limits?

    I have since arranged thru .htaccess to deny access to wp-login and wp-register to any ip except my home’s. Is that going to help/work?

    What else can i do to prevent unwanted hits from draining my resources?

    Is there anything else revealed in awstats that might be a clue? e.g. are the hits to admin-ajax to be expected?

    Some deeper background:
    I’ve been chasing similar problems around for quite some time; but is seemed to ebb and flow, and now i’m finally seeing a pattern (i’m slow!)
    I initially set up the wordpress blog for this domain over a year ago on an account with Godaddy. This was a very old-style type of account (pre-cPanel). At some point i complained/noticed slowness. When i talked to them they suggested moving to a cPanel account; claiming that would fix my problems.
    It did, at least for a couple of months. Then when i noticed problems and complained their only solution was to pay them more money for more resouces — which seems patently ridiculous for a blog that gets zero to 10 total hits per day.
    At that point i migrated it to Hostgator for a month as a test and that worked fine

    So the progression was:

    Godaddy “pre cPanel” — eventually problems
    Godaddy cPanel — problems
    Hostgator — worked fine but i was only on it for about a month
    Webhost.pro — worked fine for 6 months, then got suspended
    siteground — working fine, but it’s only been 3 days ??

    All accounts were more-or-less whatever the entry-level was offered.

    This all makes some sense: i.e. i’m using too many resouces but don’t know it, and eventually they (the provider) “catch up” with me?
    But why/wouldn’t millions of people — people with self-hosted wordpress sites at budget providers — have the same problems? Googling around seems like the 508 Resouce Limited, and performance in general, is a problem but not a huge problem; especially among people who have minimal traffic.

    There are a number of ways to limit these issues.

    I recommend reading the below link in the Codex specifically for restricting access to who can reach the login page and also try to login.

    I’d also recommend getting on a very good shared server, or your own VPS.

    I hope this sheds some light on your issue, glad to hear things are running more smoothly now.

    EDIT:

    I also should mention that although WPORG doesn’t endorse Bluehost but it is on a list of “trusted” hosts you can check out.

    i understand that i can buy my way out of any difficulties — but that seems unnecessary, after all i’m talking about a site that has perhaps 5 to 10 vistors per day. In other words there must be a smarter way to approach it. Paying more for more resouces so i can service more hackers (or whatever you want to call them) just feels wrong to me. It’s like letting “them” win!

    As i mentioned, i had already (but just 2 days ago) locked/restricted wp-login.php to my IP address.

    I keep looking around cPanel but i really don’t feel like i can find/monitor the information i would need to see how many resouces i’m using. It’s not like there’s a bucket of resouces per month (or whatever) that get used up.
    Another thing i think i notice is that the different hosting companies provide all sorts of diffent tools… for example the provider i started using a few days ago (siteground) has something the called “HTTP CPU usage statistics” in a cPanel group called “1H Software” (is there a way to attach a screenshot in this forum?); it has a table and graph of
    Realtime Usertime systime Executions Ave Secs
    hour-by-hour. Is that what i should be looking at?

    This current host, siteground seems to be running just wonderfully; but maybe i am just one tick away from being suspended… how would i know?
