Hello all, I'm finally opening a topic here as I'm getting desperate with the problems I am experiencing. Basically what is happening is that almost weekly, my main site dbzer0.com will suddenly go down with "internal server errors". I am currently hosted with Dreamhost on a VPS which means my RAM is limited to 150MB (but I can increase it at will).
Normally, those 150Mb are more than enough for 4 WordPress sies and 2 Gallery2 installations but at these (random?) points, my RAM usage will spike and all of them (which are on the same VPS) will go down.
This is definitely related to only dbzer0.com as when this happens I can't access this site, no matter how much I increase my resources and I can avoid the usage spike by simply taking down only this site (renaming the root directory to something else for example) everything else keeps working splendidly. But as soon as I rename the dir back to its original name everything stops once more)
I have tried many things to resolve it, even going as far as replacing my WP installation with a "factory default" one (so-to-speak) with no plugins and just the default theme. As soon as I restored the dir site usage once again spiked.
I suspected a DDOS but I am quite a small fish so I can't imagine why this would happen. I also checked my access.log and didn't find much evidence to support this. I suspected web crawlers and I've even ammended my bots.txt file to slow them down but this keeps going on.
I am really at the end of my wits. Is there anything you can suggest I should look for? Any way to troubleshoot this? Currently the site is down (I've renamed the dir again) and I lack ssh access as I'm currently behind a corporate firewall and lack internet access at home for the moment. So I can use only FTP for now.
I've also contacted Dreamhost about this but in the past they haven't been of much help with issues such as these and can take up to 2 days to respond so I'm not expecting help soon from there.
So please, help?
