I am using Procmail with Bogofilter to handle my incoming mail. Bogofilter works by (1) opening a wordlist BDB file, (2) locking the file (fcntl() with F_SETLK, apparently), and (3) mumble mumble. Lately, this has been failing in step 2. I’m seeing errors in my procmail log like

The machine seems to be running out of file locks. (Errno 37 corresponds to ENOLCK, “No record locks available.”)
I believe this may be a system configuration issue; is there a way to prevent this from coming up?
