RE: [hobbit] Hobbitd_client on server is crashing

["Ward, Martin" <Martin.Ward (at) colt.net>]

Solved it (possible bug?):
 
The hostname of the server was configured as tac0.lon.ws.colt.net when I
installed the Hobbit client however the machine was rebooted last week
and for reasons I have yet to figure out its hostname was reset to tac0.
 
It seems that this caused the program to crash (though it doesn't make
sense to me). I found that the name had been changed so I changed it
back and immediately the Hobbit server registered it is up and running
again!

	Hi All, 

	I am running Hobbit 4.2.0 on a number of Sun servers and
recently the hobbitd_client daemon has been crashing and leaving core
files around.

	I ran gdb according to
http://www.hswn.dk/hobbit/help/known-issues.html#bugreport
<http://www.hswn.dk/hobbit/help/known-issues.html#bugreport>  and it
came back with: 
	hobbit (at) hbt0:/opt/hobbit/server>gdb bin/hobbitd_client tmp/core 
	GNU gdb 6.6 
	... 
	Core was generated by `hobbitd_client'. 
	Program terminated with signal 6, Aborted. 
	#0  0xfee25687 in _lwp_kill () from /lib/libc.so.1 
	(gdb) bt 
	#0  0xfee25687 in _lwp_kill () from /lib/libc.so.1 
	#1  0xfee22dee in thr_kill () from /lib/libc.so.1 
	#2  0xfedd11bb in raise () from /lib/libc.so.1 
	#3  0xfedb15d9 in abort () from /lib/libc.so.1 
	#4  0x08067172 in sigsegv_handler (signum=11) at sig.c:57 
	#5  0xfee24a4f in __sighndlr () from /lib/libc.so.1 
	#6  0xfee1ae72 in call_user_handler () from /lib/libc.so.1 
	#7  <signal handler called> 
	#8  0x08063ef9 in get_ostype (osname=0x806c28d "") at misc.c:43 
	#9  0x0805b320 in main (argc=1, argv=0x80464ac) at
hobbitd_client.c:1766 

	The really bizarre thing is that it only crashes when one
particular machine connects to it and sends data. Other Hobbit clients
connect in and transfer thir core data over with no issues, it's only
this one Sun Ultra 60 that causes a problem.

	Any ideas where I might start looking?
