[Lustre-discuss] flock() problems

[Jakob Goldbach]

Hi, 

I'm using flock() extensively, but from time to time I run into
problems.

flock either hangs forever or returns -EAGAIN when called with LOCK_NB,
despite the file is not in use by others processes. 

It seems an flock() unlock was lost somehow. 

Any ideas on how to debug this ?

Thanks
