Search engine broken

[KidCharlemane]

I'm almost ashamed to post this due to the total lack of information I have but I thought I'd at least throw it out there and see if anyone has any ideas.

We recently acquired this forum that has a broken search engine. Try as I might, I can't fix it. I don't have any shell access to the machine so I have no idea what version of MySQL this board is running, etc. Essentially when you try to do a search, you end up with a "The Program Can Not Display This Web Page" error.

This is a bone stock VB installation. No hacks are installed. It is version 3.0.7. I plan to update it to 3.6.2 once I finally get login information for the server but I dont really expect that to fix the search engine problem.

Anyone got any ideas? Ive rebuilt the search engine index a couple of times and it kind of seems to straighten things out for a day or so then things go screwy again.

Thanks

EDIT

Actually forgot 3.0 had the quick stats in the Admin CP index. Here's the info.

Server Type FreeBSD Data
Web Server apache2handler
PHP 4.3.11
PHP Max Post Size 8M
PHP Memory Limit 8M
MySQL 4.1.12
MySQL Packet Size 1.00 MB

As a followup.. Search appears to work when you search for an obscure term but when you search for something that returns a lot of results, that's when you get the "This page can not be displayed" error.

This is most likely a server time and/or memory limit. You need to ask your host to increase the
'memory_limit' and 'max_execution_time' settings in php.ini. I recommend 16M and 240 resepctiovely.

Also you might want to try lowering this value:

Admin CP -> vBulletin Options -> Message Searching Options -> Maximum Search Results to Return
