Running short of concurrent connections

[sth]

I have a litespeed server 3.2.1.

On Log viewer I have many of this WARN messages:

2007-08-29 17:23:59.575 WARN [127.0.0.1:38557-0#CALCIOMERCATO] Running short of concurrent connections.

Thanks

as I said in my thread that I created before you, the reason is simply because you have to many visitors and the free version can't handle it...

free vs enterprise.
Max Concurrent Connections 150 Unlimited (500 for VPS license)

to LS support:


I'm getting this with enterprise edition. Should I keep increasing (Max Connections) ? Currently I use around 2k, looking at cacti the "Plain connections" under "used" is around 100 does these settings have anything to do to eachother?

Also I'm using smart keepalive since we have alot of images, with a 3 second timeout on the leep alive.

Also when we would purchase a ent. licence would we get some optimize help from your team for the installation or would I need to write to the forum for feedback since there is not good documentation over all settings yet?

Yeah, those are related. Max Connections around 2K is more than enough for your current usage.

If every page contains new images, you may turn off smart keep-alive. But it is not that critical.

I just started getting these error messages too!

I have only 4 low traffic sites running on LiteSpeed. Could I really be using up 150 concurrent connections?

Me too. :-)

This is lsws 3.2.2 std. Solaris 10 x86 in a Solaris Zone.

I recently upgraded from 3.2 to 3.2.2, with 3.2 it did not happen. There is not much traffic on the server. It seems that some connections are not being closed properly. When I restart the server the problem is gone but after some time it pops up again. Some strange facts:

- on the screen "Real-Time Stats" at "_Server/Requests in Processing" I see a high/growing number
- at the same time "Requests in Processing" is nearly 0 for all virtual servers. How can that be? I always thougt that _Server is the total of all virtual servers. Is that not true?

The CMS running on the server sometimes does HEAD requests to the server itself (I don't know why, seems a bit stupid, but the CMS is not maintained by me). Could it be that these local HEAD requests are not closed properly? I can see them using "netstat -a".

Anybody got an idea? Restarting lsws every few hours is not a good solution, even upgrading to Enterprise would only lead to fewer restarts.
