I've recompiled mpg123 but cannot repoduce the hang if I start the
program with the same arguments via ktrace (and if I start ktrace after the
fact, I just get what I posted in the last mail). It seems to happen about
100% of the time now. I just upgraded world as well:
FreeBSD dakota 5.4-PRERELEASE FreeBSD 5.4-PRERELEASE #29: Fri Apr 1
23:55:02 CEST 2005 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/DAKOTA64 amd64
The trace doesn't look too wierd, otherwise. There was a warning about
having libm.so.2 and libm.so.3 causing a potential conflict during
compile... It seems to find the correct lib, but later also opens libm.so.2
After we get all the libs loaded (or not, not using esd and friends)
An excerpt of the ktrace:

and so, we start playing music...
I have no clue if this helps at all. It seems like if I start some other
job, like building world, this doesn't happen. It's wierd and I've heard
of the problem from at least one other guy on ircnet, but it might just be
pilot error here, somehow...
Thanks for your time in any case.
