## Cannot Open /dev/imon

A problem has occurred trying to open the /dev/imon device. This device allows a user program to monitor filesystem activity. The File Alteration Monitor (FAM) cannot run and typical problems that occur include MediaMail (zmail) cannot automatically detect new mail and the desktop may not update itself automatically when files change.

This problem may be caused if more than one fam daemon is running at once, or it may indicate a problem with the Irix kernel.

This problem may be transitive. You should try rebooting your workstation if possible and see if the problem continues.

To resolve this situation:

- Check if fam is running with the command `ps -ef |grep fam`

- Run `fuser /dev/imon` which will tell you what process id has this device open; the process id can then be looked up with `ps -ef |grep theprocessid.` There should only be one process id, which should be fam.``

- Check for errors in the system log file by selecting “System” and from the Toolchest and then selecting “System Manager” and then “System Performance” and then “View System Log.”

Additional information about fam is available from man `fam` and the book Irix Admin: System Configuration and Operation, chapter 9.

If the problem persists, contact your System Administrator or your service provider.
