503 Service Unavailable The server is temporarily busy, try again later!

[m-mehdipoor]

Hello ,
I have this error on my server on the websites which don't have any index , and litespeed should show their directory :

503 Service Unavailable The server is temporarily busy, try again later!


I use Litespeed Web Server Enterprise v4.2.4
it is ok under apache
I have installed WHM / CPanel as well.


I have switch it to apache , then switch it again to litespeed , it becomes ok , but after a while the problem happened again.
is there any solution to resolve this issue completely !?

your lsws keeps restarting, so always have many litespeed process running, while your license is 1-CPU license.
#pstree -p|grep litespeed|wc
55 126 3575
#grep extension /usr/local/lib/php.ini
...
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20090626"
zend_extension="/usr/local/IonCube/ioncube_loader_lin_5.3.so"
extension="xcache.so"
extension="suhosin.so"
extension = "pdo.so"
extension = "pdo_sqlite.so"
extension = "sqlite.so"
extension = "pdo_mysql.so"
...
extension="ixed.5.3.lin"
zend_extension="/usr/local/Zend/lib/Guard-5.5.0/php-5.3.x/ZendGuardLoader.so"

my next suggestion:
remove xcache.so/suhosin.so/ZendGuardLoader.so
see if 503 error reduce a lot or disappears.

have you tried above ?

have you tried above ?

I had unchecked :
Zend Guard Loader for PHP ,xcache, suhosin from easyapache and ran it but it didn't help solving the issue
but as I need Zend Guard Loader for PHP and suhosin I re installed them by easyapache.

*/5 * * * * /etc/init.d/httpd restart >/dell/null 2>&1
*/2 * * * * /sbin/service httpd restart

what's reason you restart the web server every 2 minutes and every 5 minutes ?

I had done it several months ago because it got slow and by restarting it , the problem resolved .

then no other issue except this one --

this is a very unique usage of lsws --- make extreme use of lsws's graceful restart feature.

now you've fixed many php related issues (in /usr/local/apache/logs/stderr.log), maybe no need such high frequency restart now. can you try or let me try -- reduce restarts times gradually. for example, disable the 2-minutes cron job first.
