[hobbit] Hobbitd_client on server is crashing

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?
