======================================
I use Litespeed Web Server Enterprise v4.2.1 , how can I fix this problem and increase the connections on my webserver?
the server includes :
dual E5-2670 processors
64 Gig of memory.

increase
lsws admin console->Server->Tuning->Max Connections

[m-mehdipoor]

thank you.
I increased it , there is no error in my admin console now , but the websites are slow yet.
would you mind to mention what are the other things that I should check for increasing the speed of the websites in webserver?
my server's load average is > 5.82, 6.38, 5.93 ( of 32 ).

may find out some issues by just viewing it.

I attached a screen shot .
thank you.

the real-time stat looks normal.

the websites are slow yet

can you give more detail about the "slow"?

one unusual thing on the real-time stat is that there are many "Req in Processing" on quite some websites. if the website is for video or file downloading, then that's normal since one request need long time to complete.

another question: have you changed the default setting of
lsws admin console->Server->Security ?

if changed, please paste the screen shot here.
