Hmm, when a command as small as "/usr/bin/rm" does not fit into memory any more (as per your first post here) there is something seriously wrong.

If the problem goes away temporarily with a reboot chances are you have a memory leak problem. To track this sort of problems down is sometimes hard, because of the ephemeral nature of these. You could wait until the problem shows up and then use "ps -Alo vsz<,other options>" to get the "virtual memory footprint" of every process running. See the man page of "ps" for more information about possible options.

Another common source of problems are java processes, which are generally known to be memory hogs. Find out if there are java processes running ("ps -fe | grep java") and if there are some you have a likely cause for your problem.

Further lets examine the overall memory situation of your machine. Please post the output of the following commands:

"svmon -G" (only as root)

"vmstat -v"

"lsps -a"

Also examine the crontabs of all users on the machine. Maybe some memory hog is started regularly and this is whats causing your problems.

I hope this helps.

       install-memo -p <port> [-c category ] filename [filename filename ...]

DESCRIPTION

       install-memo allows the user to write one or more files as a new memo or memos, respectively, onto the Palm handheld device.

   OPTIONS
       -p --port <port>,
	      Use  device  file port to communicate with the Palm handheld device. If this is not specified, will look for the $PILOTPORT environ-
	      ment variable. If both are not found, will fall back to /dev/pilot.

       -c category
	      Install memo(s) to category category by default. Normally install-memo uses Unfiled as the default category.

       -q     Causes install-memo to be quiet and not prompt you to press the HotSync button.

       -r     Replace all memos in the category specified by the -c category option.

       -t     Use the filename as the title for the memo. (The title is the first line of a memo.)

USAGE

       The program will connect to the Palm handheld device, and write the file or files given on the command line into the MemoPad application on
       the Palm.

KNOWN BUGS

       The Palm Device may have a maximum length on memo sizes.
