After what you've told me, I'm starting to agree with you.

Still ... it's worth looking at. Can you configure things so the nsd
writes a corefile when it dies? Then, give me the full stacktrace
("thread apply all backtrace" at the gdb prompt)? Email it to me
directly so not to spam the entire list, thanks.

Hmm, interesting. I often upgrade gcc and/or glibc independently of the
kernel and haven't run into many issues.

exec could be a problem, as Tcl's exec doesn't do a clean fork/exec, so
it does force a full process copy. If you've upgraded to AOLserver
4.5.0, you should look at pushing your exec's out into an nsproxy pool.
