Let me introduce myself. I've been a .net developer for 9+ years, and I've had my share of IT support in the meantime (mostly managing SQL DB Servers, proxies, a firewell, etc), so I'm quite knowledgeable about computers and stuff.
I'm experiencing random 500 internal server errors on my wordpress installation at godaddy, linux economy plan (shared server). I've been running this wordpress blog since March 2010, and i'm getting between 100-300 hits a day (doesn't sound like a lot). Something like 30 articles, and around 300 comments so far.
The following is the list of active plugins:
All in One SEO Pack

Google XML Sitemaps
WordPress Database Backup
It seems that as time passes I'm getting more and more random 500 internal server errors, and I'm worried this may be causing visitors to go away. I just ran an uptime test here http://host-tracker.com/check_res_ajx/5208052-0/share/ out of 81 requests, 31 failed!!! More than 30%! This is more or less in line with my personal subjective findings.
I've researched a bit regarding this, it seems lots of people is having problems with wordpress in godaddy. Unfortunately they won't allow error log access to economy hosting plans, so i cannot do real troubleshooting, just trial and error. How would you suggest troubleshooting this problem? I'm seriously thinking about moving to a different hosting at this point.
Any suggestions will be highly appreciated.
