I've just found an issue which caused rt_queue_delete() to leave
dandling mmapped segments when attempting to remove a busy queue (i.e.
still bound to another descriptor in user-space).
Could you resync with v2.3.x (or trunk) head revision and try again?
TIA,
After resync and running main once:

I'm going to re-check that my build was clean, but I think so.
Ok, it's not impossible that the initial fix caused a regression on the
registry's /proc unexport code. I'm going to check that on my side too.
Looks more like some unrelated, forgotten-to-rebuild RT module now.
Things run smoothly at the moment, I'm unable to reproduce any of the
earlier issues.
Ok thanks, so far, no reproducible issue here too, but I will leave the
test running for a few hours just in case.
Hm, updated my machines to 2.6.20 and 2.3.0 rev 2222. I still see ( less
frequent?) some backtraces occuring on my console, either during reboot
or sometimes when running the testprogram and reloading the modules.(see
dmesg snippet below) The Celeron M still crashes often totally.
My main-application still freezes the SMP mashines if I have 'priority
coupling' enabled in kernel-config. Using trunk makes things even worse.
The pc will crash during startup of my app, the testapp I sendt you
works, but i can not shutdown the pc afterwards, because it freezes
completely when terminating kdm.

dmesg tells me the following (2.3.0.2222, 2.6.20, SMP):
