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.
I had this happen once before with an INN 1.5.1 server (running on a Sun Ultra-1, Solaris 2.5.1) with its spool on an F230 running 4.2a. After about a day of investigation, I simply rebooted the Sparc and the problem went away. The server and innd process have been running since Dec 14 now, and the problem has not reappeared since. You didn't mention what platform runs your INN server.
