pls download and install debug version of your current installed lsws version.

e.g.

http://www.litespeedtech.com/package...nux-dbg.tar.gz (for lsws 4.1 ent x86_64 linux version)

also install gdb (gnu debugger) and mailx package (e.g. via yum install). when this happens again, the needed info will be sent to us to figure out what's wrong.
