Is this a server or client problem? Could it be hardware related? There is nothing in my /var/log/messages or syslog to indicate a hardware problem. The UBB appears to be functioning fine.

Mmmmm... if I didn't know better, I'd say you were running NT with the ISAPI DLL, but clearly you're on Unix. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
How frequently do errors such as this occur?

A simple grep in the error log shows 96 occurences of "compilation aborted" since March 1. It seems that is printed twice per error so I'd guess 48 times this month.
Grab as many of those errors as possible, stick them in a text file, and mail it to []charles@infopop.com[/], including the URL to this topic.. I'd like to look at all of the errors.

All of the errors don't exist - if the modules being referenced had the problems that the log says they're having, perl would flat out NOT operate on your server.
We've only seen one thing like this - the ISAPI DLL of ActiveState Perl throws errors EXACTLY like this......
Are you using FastCGI / SpeedyCGI or any similar tool that "speeds up" CGI processes?

I'm going to check my February and January logs to see when this started happening. My hunch is that it started recently because of the increased load caused by Recent Visitors. Just a hunch.
Well, just because you have mod_perl compiled in, that doesn't automagically make UBB run under it... thank goodness. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
Does your UBB randomly forward people to other pages, duplicate output (i.e. one page's contents appended to the bottom of another) or do anything else freaky and otherwise odd?

It performs normally other than the occasional burp and those error messages.
When you mentioned mod_perl I remembered reading that UBB doesn't support that, but I wasn't sure how to tell UBB to use or not use mod_perl's features.
I'm starting to believe this is a resource issue rather than anything to do with UBB. I have looked back in my error logs and I have seen these error messages well before I upgraded to UBB 6.X, which generally increased the system load.
I have adjusted the Apache conf variables:
RLimitCPU and RLimitMEM to "max max" to see if this resolves the issue.
I added a cron job to do a 'ps -fl' and 'uptime' every minute. I seem to have a correlation with a large number of sys_flock calls being made and a larger load and these errors occuring.
Does this ring any bells for you as to being a UBB issue?
If the errors occured before going to 6.1 (which is when many issues like this made themselves known), then chances are it's something with your local setup that is going awry than something that the UBB is directly causing.
The file not founds within the logs are just that - clients requesting files that aren't there... <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />

I believe I have finally tracked down the problem. The search function is causing the problem. The search index's are very very large, ie: up to 30Mb. for each forum!
For the time being I have turned off the search function until I figure out how to resolve this.
FYI, to troubleshoot this I used the Apache mod_status module and captured server-status output, with ExtendedStatus On, in a file through a cron script with the text based web browser 'lynx'. After analyzing the captured data around the time of the error messages I noticed that 3 searches were running at once. I tried this myself by running searches in 3 separate browser sessions on the largest index file and voila, I reproduced the problem.
Any ideas how to resolve this other than pruning posts? I read that you've changed how indexing works in 6.2.2. Is this now scraped because 6.3 is on the way?
