Server is restarting multiple times a day



I builded the server from @Slavik 's great manual.
Web server lshttpd on CentOS-64-64-minimal is automatically restarted

At [01/Nov/2013:03:12:31 +0100], web server with pid=25242 received unexpected signal=11, a core file is created. A new instance of web server will be started automatically!

Please forward the following debug information to

Server: LiteSpeed/1.2.6 Open
OS: Linux
Release: 2.6.32-358.18.1.el6.x86_64
Version: #1 SMP Wed Aug 28 17:19:38 UTC 2013
Machine: x86_64

If the call stack information does not show up here, please compress and forward the core file located in /tmp/lshttpd/.

Howdy John,

Thanks for reporting the bug. This bug is very similar to one that has been reported on the OpenLiteSpeed Google Group, and the developers are working on it. In the future, if you encounter something that is obviously a bug, the Google Group or GitHub are probably the best places for you to let the developers know.
