Hi Fellow Admins,

I keep getting the following error messages during backups (I use
dump) on my Alpha 3000/300 - OSF3.2a:

  dump: Date of this level 0 dump: Thu Dec 07 23:43:21 1995 EST
  dump: Date of last level 0 dump: the start of the epoch
  dump: Dumping /dev/rrz0a (/) to standard output
  dump: Cannot get semaphores
  get_semaphore(): semget() for fifo_free_semid: No space left on device
  dump: SIGTERM received -- Try rewriting
  dump: Unexpected signal -- cannot recover
  dump: Cannot remove semaphores
  remove_semaphore(): semctl() for fifo_free_semid: Invalid argument
  dump: Cannot remove shared memory
  remove_shared_memory(): shmctl(): Invalid argument
  dump: SIGTERM received -- Try rewriting
  dump: Unexpected signal -- cannot recover
  0+0 records in
  0+0 records out

The backups go along fine for a while, sometimes several weeks, sometimes
for only a few filesystems before this error occurs. Once it's happened,
the only way to fix things (that I have found) is to reset the machine.

Has anyone seen anything like this before? Have any suggestions?

Many thanks.
Lyn
