multiple 503 errors
 

Hello,

On many our sites in logs we see such errors like this one below:

2013-02-11 10:12:29.870 [INFO] [x.x.x.x:40365-0#APVH_www.****.eu] connection to [/tmp/lshttpd/APVH_www.****.eu_Suphp.sock.069] on request #1, confirmed, 1, associated process: 21442, running: 0, error: Connection reset by peer!

and this one:

2013-02-11 10:34:13.427 [INFO] [x.x.x.x:56727-0#APVH_]www.****.eu] connection to [/tmp/lshttpd/APVH_]www.****.eu_Suphp.sock.752] on request #0, confirmed, 1, associated process: 30217, running: 0, error: Connection reset by peer!

of course Litespeed restarts almost every 1 minute...

How to solve this problem?

I don't use any of this from this link. Those errors started after curl update to version 7.29.0 (directadmin). Earlier was everything fine.

try re-build matching PHP to be compatible with underline curl libraries (updated).

Well i used LS php compiler to rebuild php but still no effect (LS 4.2.1 and PHP 5.3.19)

can you create a simple php script which contain curl functions, see if can reproduce the 503 error easily ?

We will test this curl today, but i found also this:

and on multiple sites...

Problem was with curl 7.29.0. after downgrade to 7.28.1 all 503 errors are gone. So there is a problem with directadmin, curl 7.29.0, litespeed 4.2.1 and php 5.3.19.

Can you run 5.3.19 + curl 7.29.0 with Apache and see if problem persists?

On normal apache with curl 7.29.0 everything is ok.
