Thanks for the info.
May I ask you a few questions:
o how long is nfsend running before it segfaults?
o does the crash occur, while working with NfSen (using a web browser)?
o does the crash occur over night. ( nobody is working )
It seems as a signal is not handled properly. I will check, if I can change
some Perl code.
