We recently (~6-8 weeks ago) put up a F520-110 Filer running 5.0.1 software. When I try to run INN (InterNetNews) 1.7.2 and put it's overview files on the filer, I get Overchan hanging very regularly on a fcntl(F_SETLK,...)/fcntl(F_SETLKW,...) loop.

My question for the assembled guru's is: Is anyone else seeing this? What other information should/could I supply to help?

Yes, we have seen this, with an F330 running 3.1.5. I "fixed" it by simply removing the code that locks the overview files - would rather risk having two processes access the file at the same time than having these loops. As far as I can see, all we risk is one of the readers getting inconsistent overview data for a group - we can live with that.

We recently upgraded to 4.3.3D2 - haven't tried using the locking code again after this upgrade.

I had the same problem with qmail and various 4.2 versions. An upgrade to 4.3R1 made the problem go away and the filer in question has been running that release since then.

The 'running 5.0.1 software' bit above may be another chapter in the long saga of NFS locking :-)
