I'll it try now. This will take a few hours.

No, if I use the task manager pid of that sh.exe (3228) I also get:
$ strace -p 3228 > p3228.log
strace: couldn't attach to pid 3228<504> for debugging

but the funny thing is that the sh process with windows pid 3228 is not
mentiones in a
$ ps -aW
at all.

I'll stop that process now and try the 0906 snapshot.

Thanks
