Troubleshooting NFS Services
Common Problems with NIS+
Chapter 8 321
If You Have Insufficient Memory or Disk Space
❏ As a short-term solution to free up memory, kill all unnecessary
windows and processes. If necessary, exit your windowing system
and work from the terminal command line.
Use the ps -el command to check the size of running processes.
Sometimes programs develop memory leaks and grow very large. If
necessary, compare the size of processes on your host with processes
on a host that is not having memory problems to determine whether
the processes on your host are growing too large.
❏ As a long-term solution, install more memory or swap space, or move
your NIS+ server to a system that has more memory or swap space.
❏ If you have a shortage of disk space, clean out the /tmp directory and
remove any unnecessary files. Remove core files from the root
directory and home directories.
❏ If you do not checkpoint your transaction log regularly, it becomes
very large. However, in order to checkpoint your transaction log, you
need sufficient disk space to allow NIS+ to make a complete copy of
the log before removing it. You might have to add disk space to your
server before checkpointing the log.
To checkpoint the log, issue the nisping -Ca command. If your
transaction log is large, or if you have a large number of replica
servers, the nisping command can take a long time. It is
recommended that you create a cron job to run nisping -Ca every
night while the network is not busy.
