Hello Norbert,
Perhaps, this would have been better placed in some networking forum.
http://community.qnx.com/sf/discussion/do/listForums/projects.networking
Even then the experts there would need more detailed informations such as :
-used OS Version and patchlevel
-target (x86, ppc ....?)
-how did You started which qnetstack (l4 or compat or both)?
Did You tried command-line options to Your qnet ?
Exact network topology (crossover, switches bridges etc ...) ?
Outputs of:
qconfig (from your Dev-Host, if avaliable from Your target)
uname -a
nicinfo
pidin -p io-net
ls /dev/io-net/
cat /proc/qnetstats during after Your pidin hang/delay ?
This would be at least a starting point.

for example try :
#sin toomuch
or
#sin sin

So that is sin under nto.
Hope this helps.
