Hi Michael,
The semaphore protects tasks within nfsend, that must not interfere with other
events.
If you can not get the semaphore, you need to search for OS/kernel issues -
either
too many semaphores already in use on that system or some policies preventing
acquiring a semaphore. If you ignore this error and any interferences of events
happen,
you risk to corrupt your data.
Regards
