hi,
I fixed the issue with lighttpd and got it up and running 
Now for testing proposals I use lighttpd and apache… with both
webservers I have the problem that e.g. opening a ticket is very slow
(with both webservers) and the CPU usage increases to 100% …
Does anyone has an idea how to fix this? Its a brand new server and i
dumped the mysql data in it…
Thanks for any help!
best regards,
Raphael
RT debug log. mysql slow log.
Very slow? How slow? Hangs forever or 1 minute? How big is your DB?On Fri, Jul 11, 2008 at 12:47 PM, Raphael Loziczky rl@greentube.com wrote:

How can I enable RT debug log? mysql error log shows no errors…
very slow means that it hangs for about 1 minute - we have our old
system running with the same db which is much faster! (on old hardware)
the mysql dump is about 20 gigs… when I made the dump from the old
system I had to use “force recovery” mode with mysql to get a working
dump. maybe thats the problem?

thx for the tip, Arran but it’s currently running with mysql 5.0.22 so
the broken query optimizer can’t be the problem…
some more ideas?
thanks,
Raphael

If your new mysql instance running mysql 5.1 ?If so the query optimizer is slightly broken, this can cause issues
with queries. Try with a version 5.0.Thanks,

Actually, 5.0.22 is known to have some AWFUL query optimizer bugs. My
recollection is that they were fixed in 5.0,45 or so

ok updated to 5.0.45 but still the same problem 
Turn this on in your my.cnf file so you can see if it’s the MySQL queries:
#log_slow_queries = /var/log/mysql/mysql-slow.log
