Server lag and PB

[pieman]

I currently run several COD 4 and COD WAW servers for several months now we have been experiencing extreme lag on all the servers and roughly at the same time on each.
I've seen several posts on various forums about this but so far no solution.

It's gotten to the stage now where we have had to turn PunkBuster off to get rid of the lag.

Does anyone have a solution to this problem or are there any settings I can add to remove it as we are now infested with cheaters and it's a toss up between cheats or lag

in the pbsv.cfg file you could check these settinmgs to make sure you are not causing your own issues.

pb_sv_CvarFreq 2 //[# of range checks per minute]
pb_sv_CvarLogging 3 //[1=Reg. Log, 2=Var Log, 3=Both, 0=Neither]
pb_sv_CvarWalk 2 //[0=disabled, 1-4=Walk through obtained Cvar lists]
pb_sv_CvarUserPulse 30 //[Frequency to auto-send CvarUser (minutes)]
pb_sv_CvarChangedPulse 45 //[Frequency to auto-send CvarChanged (minutes)]

and reduce the volume of screenshots with these

pb_sv_AutoSsFrom 180 //[Min # of seconds to wait before requesting next ss]
pb_sv_AutoSsTo 1200 //[Max # of seconds to wait before requesting next ss]
pb_sv_AutoSs 1 //[0=No, 1=Yes (default=0)]
pb_sv_ssLogging 3 //[1=Reg. Log, 2=SS Log, 3=Both, 0=Neither]
pb_sv_ssTimeout 0 //[Seconds]
pb_sv_Sleep 60 //[# of Milliseconds (default=60)]

these changes helped me past similar issues we now run 4 fairly lightly loaded cod4 and waw servers oin an old dual core server with no PB lag.

Yeah those are the recommended settings from Punksbusted which we are running and we have autoSS turned off.

in that case how about some info to work with.

Server spec
number of server processes and the number of slots per server.
wan connection

these will help to start with.

[pieman]

Dual Xeon 3 Ghz CPU's
4 GB RAM
WAW server has 40 slots but lag happens when there are as little as 2 people on.Wan Connection is 2 TB

Seriously it's not an issue with my server.

This happened on my previous server we built a new server 2 weeks ago thinking it was a server problem but we still get it with this server with a clean install and all recommeded PB and Punksbusted configs.

There are alot of posts about this on various forums and the IW forums but no solutions so far :(
