There appears to be a bug in 2.2.5 with the ptrace stuff. It appears to only happen on SMP systems. I have found that the process being straced ends up eventually getting stuck in the stopped state. It's quite easy to reproduce:
[sroot@oof:/]# strace yes > /dev/null
...wait about a minute or so...
(in another console)
[sroot@oof:/]# ps auxw | grep yes root 11521 15.4 0.3 936 396 3 S 17:59 0:34 strace yes root 11522 49.7 0.2 836 268 3 T 17:59 1:51 yes root 11533 0.0 0.2 952 312 4 S 18:01 0:00 grep yes
kill -CONT 11522 would make it continue again as normal until the next time it occurs.
(Using strace version 3.1.0.1)
