in lsws.txt:

2016-10-14 11:10:47.407 [INFO] [/usr/local/lsws/bin/httpd] set LVE_ENABLE=2.

so CloudLinux is running ?


please Check If The "nobody" User Is Being Limited By LVE:

checked , not limited .

 

[NiteWave]

looks like shortage of some critical resources.

please check with
#df -h
#df -hi
#top -c

when litespeed can't restart

/home3 is full:
/dev/sdc1 459G 435G 237M 100% /home3

only 237M available

/var/share/optimumcache/DiskDescriptor.xml is full,
15G 15G 0 100% /var/cache/optimumcache

0 byte available.

maybe you can disable cloudlinux's optimumcache to see if any difference.

Does not looks to be related to cloudlinux or litespeed service. How do you check a site? With browser? What if you connect to port 80 from your machine and to port 80 from server itself? Maybe you are blocked by some smart firewall or so?

again on another server this problem occur , litespeed hung , even restart not help , but when kill all litespeed process and restart again problem resolved.

Check and ensure there is no disk full issue.
also check log file to see what happened.

If you are using cpanel, make sure to upgrade to latest build of 5.1.10
/usr/local/lsws/admin/misc/lsup.sh -f -v 5.1.10

You can also try this if it applies to your situation:

[pardis]

this problem not resolved. this issue occurred on two server .
all things checked and not find any date related this issue.

 

[NiteWave]

lsws 5.1.11 just released.
http://www.litespeedtech.com/index.php/products/litespeed-web-server/release-log

• [Bugfix] Fixed an issue where cPanel killed LiteSpeed when applying configuration changes, such as adding an add-on domain or sub domain.

if still exists, may need login the server for further investigation.

 

[pardis]

I can't see new version in our admin panel.

please refer
https://www.litespeedtech.com/suppo...iki:admin:upgrade-notification?s[]=autoupdate
"We normally wait a week or two to push it to autoupdate. Then your web server will show information about the available upgrade and send you an upgrade notification. After this, you can do the upgrade right from the Admin Console."

before that, you can do it manually at command line:
#/usr/local/lsws/admin/misc/lsup.sh -f -v 5.1.11
