From the FAQ:

    Q9:
    Machines at my site share a single /tmp directory.  More PVM daemons
    can't start up because the file /tmp/pvmd.uid# already exists.

    A9:
    Get release version >= 3.2.3.  This includes a compile-time option to
    change the name of the file in /tmp to /tmp/pvmd.uid#.hostname, avoiding
    the conflict.

    If you want this option enabled for all machine types, edit
    src/Makefile.aimk and add -DSHAREDTMP to the (uncommented) OPTIONS=
    line near the top.

    If you want it set only for certain architectures, edit the config
    files for those machines in conf/*.def and add -DSHAREDTMP to the
    ARCHCFLAGS= line in each.

    You'll need to rebuild the distribution and relink any applications
    using libpvm.
