You need to check error_log & stderr.log.
If you use cPanel, those log files are under /usr/local/apache/logs/

Maybe PHP crashed, or resource limit has been reached.

i see following error, can you explain about them?

that's normal, you can grep "oops" in error_log for messages related to 503.

please post the message between the 2 lines

 

[3245]

i Highlights for you
red: this is just one site.

 

[3245]

i see following error in CSF, this problem may for same 503 error?

 

[NiteWave]

you can try that as suggested by csf -- create a swap file.

I think the 503 error is more related to your design website

is the mysql fast enough ? does the php script consume too many memory ?
have to be more specific and need more information to pin down it.

 

[3245]

if you need more information, i can provide you.
we have 64GB ram
12core CPU.

 

[NiteWave]

ok, please PM the root access.

please refer http://www.litespeedtech.com/support/forum/showpost.php?p=74500&postcount=3
"503 Error often due to php crash
some php extension may cause 503 Error
please check php.ini, what extensions you've loaded, and post the list here so we can have more information about the error"

 

[3245]

i attached php.ini
Please see.

 

[NiteWave]

suspected extensions in your php.ini:

extension="suhosin.so"
zend_extension="/usr/local/IonCube/ioncube_loader_lin_5.3.so"
zend_extension="/usr/local/Zend/lib/Guard-5.5.0/php-5.3.x/ZendGuardLoader.so"
extension="ixed.5.3.lin"

please disable ZendGuardLoader first.
see if 503 gone.

is still happen, then disable the rest 1 by 1, to identify which one is the culprit.

 

[3245]

if i disable ZendGuardLoader, so how i can use zend coded in our sites?

 

[NiteWave]

please refer:
http://www.litespeedtech.com/support/forum/showthread.php?t=5765
"3.if have to load ZendGuardLoader, then above is a workaround to modify the source code of Gallery 3!"

i.e., you have to modify the php source code. note: this is not a litespeed or lsapi specific issue, it also apply for apache. it's an issue of ZendGuardLoader itself.

 

[3245]

problem was for mod_security
how i can disable mod_security in litespeed ?
becuase cpanel staff tell me mod_security is disable in apache, but in litespeed still is enable,
how i can sure mod_security is disable on litespeed?

Thanks.

Thanks
so when i disabled mod security in Apache, then run build match binary, then mod security is disabled on litespeed also?

Thanks.
