Seth, 
I read your mantis and made a comment in it.  I will do some more looking now 
that I understand the problem and make sure my issue is indeed the same thing.

For some reason removing my domain name and using my IP address in it’s place 
on one server appears to have helped but that could be a false impression I got 
since things were working fairly well before I did that.

My experience to date is that until I reboot my servers they stay in a messed 
up state and lots of thing go wrong like IM’s get totally dropped, and tp’s 
stop working even between regions on the same server with messages saying they 
can not establish a connection.  Oddly enough I can usually tp to LBSA and 
often then get to the failed region.  If I reboot everything, then it is back 
to normal until this happens again.

Sometimes I find the regions already like this when I log on.

Tom

Subject: [Opensim-users] Need help with a serious LAG problem

This is a known problem, and one that has been previously reported.  See the 
following Mantis bug report;  http://opensimulator.org/mantis/view.php?id=7393


I invite you to add your experiences to the Mantis report, and ideally if you 
can collect any data and provide it back to the devs it could be a big help in 
identifying what specifically is going on.  The more data that shows what is 
happening the better chance they have of finding the cause.


I have seen this issue happen when users visit a sim, and they have poor 
network connections, such as those using satellite or tethered cell phones.  We 
have also seen this with some visitors from university dorms where there 
appears to be throttling on their end, as well as others to varying degrees.  I 
have been monitoring this long enough I know of several visitors that when they 
arrive I know problems are likely to follow soon.


As you have seen, this problem seems grow worse as the number of avis in the 
region increases.  For a while things will be ok, but if you have console 
access and monitor the throttles that is generally one of the early indicators 
that problems may arise.  If things clear up quick enough the sim will recover 
with little to no visible impact in the region.  However once things go on past 
a certain point, then you will see SimFPS and time dilation affected, this is 
then when chat lag and movement within the region are affected for everyone.  
If the problems are bad enough then threads get stalled and you sill see a 
large number of avis get kicked out at the same time due to timeouts.
