You don't say which specific version of 9.5.0. That version is not 
released which means that you must be running an alpha or beta version 
of it. You should have gotten a core dump. If you didn't there should be 
some information in the ARM about what you need to do to get that to 
happen. Is there absolutely nothing in the logs whatsoever? Are you 
running out of memory? You may need to limit your memory use. Again look 
at the ARM.

If you do get a core dump, file a bug report at bind9-bugs at isc.org so 
that they can take a look at it.
