Im looking for an expert server admin with advanced experience with lighttpd to look at my 2 servers which power my 2 very high traffic sites. These servers constantly display 500 errors, which my current server tech claims is due to poor site CMS script which overloads the server. I find that very strange, because one server has an average load of 3-5 on an 8 core machine, and the other has an average load of 0.7 on a 4 core machine. What bothers me the most is the fact that it shows 500 errors during off times (at 1-2am) more often than peak times.
Im looking for someone to evaluate the issue, by looking at the server configs and suggest/implement improvements.
