Internal Server Error when performing search

[EdK]

Receiving "Internal Server Error" message when performing a search.
Also, site is vey slow. Haven't used the site in a few months and never experienced the slow response in the past.

The slow response time has been a problem for the site for quite a while now. There are times when it seems to sail right along and other times it can't get out of its own way.
