[syslog-ng]Mystic crashes of 1.5.10

[Andreas Schulze]

Hello Bazsi,

thanks a lot for the stats() feature in the new version.
But unfortunately 1.5.10 crashes a few minutes after starting.
We are running your software on SUN Solaris 8 boxes.
I read about a similiar problem with Linux boxes some weeks
ago in this list.

For your convenience the backtrace is attached.

The calling deps between #17 and #1 can differ in each core.
But it crashed _always_ in
	__sigprocmask () from /usr/lib/libthread.so.1
And it crashed _always_ by receiving SIGKILL.

Seems a little bit mystic for me, because I don't know
why and who's sending the SIGKILL.
Coredumps by SIGSEGV are more familiar to me :)

Thx. for a fast fix --Andreas
