Re: [Nfsen-discuss] Can not get semaphore: at libexec/Nfsync.pm line 48.

[Peter H. <ph...@us...>]

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
