I need global for 'time'. I thought it might not be necessary after I  
made my last post but I got the following when I took it away:
/var/log/interchange/debug.log.1:Safe: 'time' trapped by operation  
mask at (tag 'perl') line 2.

I did already replace Dumper with uneval (not as pretty though).  
Thanks. It's fun watching the slow pages add up.

I'm still having a tough time running in RPC mode. It will run along  
fine for hours and then the load average will shoot up to 10 or 15 on  
all or most of my IC servers. I do not see anything in the log files.  
I killall -9 interchange and restart and all is fine for a while. If  
I switch back to HIGH mode I don't see these problems but the  
response times are slower overall.

At one point we narrowed the problem down to a specific page. That  
page had a PERL block that counted hits from HTML broadcast e-mails  
and redirected to the desired link. In the block I had "use CGI;" and  
saw "Safe: Undefined subroutine CGI::delete" in the logs at the line  
where the "use CGI' was. An Internal Server error was presented to  
the client. When this problem came at all it came intermittently  
about once every 20 times. When I took out "use CGI" we could not  
reproduce the errors. I rewrote the page to not use "use CGI" and  
thought all of our problems were solved.  I just now tried to rewrite  
the page the old way but could not make the errors. I also could not  
create another test case to produce the errors with "use CGI'.
