Graceful restart not so graceful
 
1) Ubuntu 10.04LTS amd64
2) 4.1.10std
3) PHP 5.3.2-1ubuntu4.10 FCGI+PHP-FPM

2012-01-18 21:06:12.384 [ERROR] HttpListener::start(): Can't listen at address *:80: Address already in use!
2012-01-18 21:06:12.384 [ERROR] HttpServer::addListener(*:80) failed to create new listener
2012-01-18 21:06:12.384 [ERROR] [config:server:listener:*:80] failed to start listener on address [ANY]:80!

I did not have this issue with <4.1 versions. I either need to manually stop and restart lsws, or wait a good while (a minute or two at least).

Have you tried LSPHP (LSAPI + PHP) which is much better than FCGI+PHP+FPM?

Well, it is not better in my situation:
-running on low volume and -std, performance does not matter much (and do you have benches LSAPI vs FCGI+PHP+FPM?)
-having to compile a new LSAPI module each time there is a PHP upgrade is a PITA
And I did not have this issue with previous versions of Litespeed even using FCGI.
thanks for your help!

is there another process already listen to port 80 ?

please run
#netstat -ntlp

Before restart:
Code:
# netstat -nlpt|grep ":80"
tcp6      0      0 :::80                  :::*                    LISTEN      9852/litespeed (lsh
After restart:
Code:
# netstat -nlpt|grep ":80"
tcp6      0      0 :::80                  :::*                    LISTEN      9852/litespeed (lsh
# netstat -nlpt|grep ":443 "
tcp        0      0 188.165.55.67:443      0.0.0.0:*              LISTEN      9852/litespeed (lsh
tcp        0      0 87.98.157.151:443      0.0.0.0:*              LISTEN      9852/litespeed (lsh
And 443 is OK, 80 is not.

After a couple minutes, another graceful fixes port 80:
Code:
# netstat -nlpt|grep ":443 "
tcp        0      0 188.165.55.67:443      0.0.0.0:*              LISTEN      24034/litespeed (ls
tcp        0      0 87.98.157.151:443      0.0.0.0:*              LISTEN      24034/litespeed (ls
# netstat -nlpt|grep ":80 "
tcp6      0      0 :::80                  :::*                    LISTEN      24034/litespeed (ls

Can you paste few entries around (before and after) the ERROR entries you pasted above? Just to see any trace/cause of the problem.

Ok. Looks like lsws performance isn't a selling point to you :)

Anyway, lsphp is up to 30% faster than fcgi+php and 50% faster than apache mod_php (http://www.litespeedtech.com/php-litespeed-sapi.html)
