someone restarted lsws from admin console. however, gracefully restart will NOT cause 'server not found' as all the active requests will be handled till the completion.

pls post a screenshot of 'server not found' to be clear. it should not from lsws.

[webizen]

looks like your lsws is running on server. you may want to check on the server itself such as 'curl -I http://hostname' or 'curl -I http://localhost'

you may check http://support.mozilla.org/en-US/questions/749336 for the message 'Firefox can't find server at ...'

 

[TheMask]

# curl -I http://localhost
HTTP/1.1 301 Moved Permanently
Date: Wed, 11 Apr 2012 23:32:28 GMT
Server: LiteSpeed
Connection: Keep-Alive
Keep-Alive: timeout=5, max=100
Location: http://www.*****na.com/
Vary: User-Agent

now i see.. this problem happend when server load 7-9 or high...

 

[webizen]

if you get response from curl but firefox can't find it, then that's not the problem of lsws. read the link from mozilla posted earlier.

 

[TheMask]

ouw i will look this command when error appear.

 

[TheMask]

# curl -I http://flexkomkobi.com
curl: (6) Couldn't resolve host 'flexkomkobi.com'

i take this error now.
when server load high to 7.00

 

[TheMask]

lol but i know my dns working well
but webserver dont answer when load 7.0+

 

[webizen]

It is your DNS issue. When server (host webserer and DNS) load is high, DNS fails to respond! This is NOT an LSWS issue.

You should move NS to a different server to avoid this.
