All network tests now purple - update
I rebooted the machine now after having installed the update and now I see this in bb-network.log:
*** glibc detected *** corrupted double-linked list: 0x0000000080051ae0 ***
No core file.

This does indicate some sort of bad memory access by bbtest-net. Unfortunately, it doesn't provide much clue about what caused this problem.
Since it's glibc, I suppose it's on an Intel-based system ? In that case, it would be helpful if you could pick up the "Valgrind" utility; it is included in some Linux distributions, but you can also grab it from valgrind.org. Once you have it, you can run bbtest-net with the command
valgrind --log-file=vlg.log bbtest-net [any bbtest-net options]
If there's a memory access error, it should catch it right away. I'd be interested to see the logfile it produces.

This s390x architecture (64-bit Mainframe). The web site makes no mention of the architecture, but I'm checking with the Linux for zSeries list to see if anyone has ever used it on the mainframe.
If it looks like it will work, I'll create the log file and send it.
Thanks.

:( Any other ideas? Valgrind is not supported on the s390/s390x architecture (configure fails with a message to that effect).

Hmm ... perhaps you can run it inside gdb. su to the Hobbit user, then run
$ gdb ~/server/bin/bbtest-net gdb> set follow-fork-mode parent gdb> run --debug [other bbtest-net options]
When it crashes, use the "bt" command to get a stacktrace. Unfortunately that might not tell me much because it could very well be that the problem happens some time before it is detected.
Also, could you send me your bb-hosts, bb-services and hobbitserver.cfg files ?

OK, the information has been collected and sent privately.
Thanks.
