[RESOLVED] Restart problem (old server isn't killed)
After swith to Litespeed 4.0.12 enterprise (before i use standard version) i have problem with restarting
Litespeed version: freebsd 64bit ent 4.0.12
Before restarting:
Code:
root@core2:~# ps aux |grep lshttp
www 33858 0.2 0.1 11572 6504 ?? D 8:40PM 0:00.09 ./lshttpd (lshttpd.4.0.12)
root 33854 0.0 0.1 10412 5248 ?? S 8:40PM 0:00.01 ./lshttpd (lshttpd.4.0.12)
After press restart in admin pannel
Code:
root@core2:~# ps aux |grep lshttp
www 33858 4.6 0.1 13036 7536 ?? SN 8:40PM 0:04.40 ./lshttpd (lshttpd.4.0.12)
root 33854 0.0 0.1 10412 5256 ?? S 8:40PM 0:00.03 ./lshttpd (lshttpd.4.0.12)
root 34344 0.0 0.1 10412 5252 ?? S 8:41PM 0:00.01 lshttpd (lshttpd.4.0.12)
www 34346 0.0 0.1 10492 5668 ?? S 8:41PM 0:00.03 lshttpd (lshttpd.4.0.12)
And after while (when old server is ready to end):
Code:
root@core2:~# ps aux |grep lshttp
www 33858 0.0 0.1 12572 7076 ?? SN 8:40PM 0:04.42 ./lshttpd (lshttpd.4.0.12)
root 34344 0.0 0.1 10412 5252 ?? S 8:41PM 0:00.02 lshttpd (lshttpd.4.0.12)
www 34346 0.0 0.1 11636 6680 ?? S 8:41PM 0:00.48 lshttpd (lshttpd.4.0.12)
As we can see pid 33858 is still running and even i send kill 33858 it don't do anything. Also all lsapi process are runing (php, ruby)
i tested this on 4.1RC2 and there problem don't exists.

due to cPanel 11.25 graceful restart issue, we have changed graceful restart of 4.0.12 to finish all pending requests completely, my guess is that there are still requests in process. It takes longer for the lingering process to quit.
Please strace and lsof the running process. if there are active ESTABLISHED connections to port 80, it is still serving requests.

Please try a force reinstall from web console to apply the latest build of 4.0.12, add some code to deal with it.

(id = belongs to 1 litespeed server)
this is how it looks after few restarts. php isn't stoped too.
by the way swithing version don't change symlink to lscgid  and after that we have (after this test i checked to rc2 for another test)
Code:
www 88224 2.9 0.1 19208 9548 ?? D 11:32AM 0:02.18 lshttpd (lshttpd.4.1RC2)
root 88222 0.0 0.0 11972 4012 ?? S 11:32AM 0:00.03 lshttpd (lshttpd.4.1RC2)
root 88223 0.0 0.0 2568 716 ?? S 11:32AM 0:00.00 httpd (lscgid.4.0.12)
