503 Error With LiteSpeed

[madihrb]

Hello,

We switched our cPanel based Apache to LiteSpeed.

Everything is going good but the problem is that we receive 503 errors regularly. The error normally looks like:

Normally it come during software installation or posting in wordpress.

503 Service Unavailable

The server is temporarily busy, try again later!

Unfortunately I don't understand the post.

Can someone help me to resolve the issue?

Is there anything logged into lsws/logs/stderr.log? If is, those messages should help identify your problem. Please check the lsws/logs/error.log as well.

Usually, 503 errors are caused by malfunctioned external application (like php). In such a case, the following should help troubleshooting.

lsws/logs/stderr.log
lsws/logs/error.log

The above files does not exists in my system.

Secondly one more thing, LiteSpeed is running since 8 days and no client complained.

But I received DDOS attack, after that attack, 4 clients have complained that error.

May be that DDOS attack had done something?

for cpanel server, it is
/usr/local/apache/logs/error_log and /usr/local/apache/logs/stderr.log

The below errors from /usr/local/apache/logs/stderr.log

Regarding the error

2010-12-15 13:59:49.955 [STDERR] lsphp5:/home/hhcarder/public_html/install/index.php: symbol lookup error: /usr/local/lib/php/extensions/no-debug-non-zts-20060613/suhosin.so: undefined symbol: zend_atol

It seems the suhosin module built by cPanel easyapache does not match lsphp5 binary. pls install latest lsws 4.0.18 and build matching php from there.
