Error: Three common causes of FATAL ERROR (MSEEK)
Solution or Workaround
Why is the user bailed out of ARCEDIT with "FATAL ERROR (MSEEK)"?
Usually the message is caused by one of the following:
Disk is full.
Not enough swap space is available.
The /tmp directory is full.
1. Remove unnecessary files from hard disk to free up some space.
2. Increase swap space.
3. Delete files in /tmp that are not in use.
