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.

native2ascii

native2ascii(1) 					      General Commands Manual						   native2ascii(1)

NAME

       native2ascii - native to ASCII converter

SYNOPSIS

       native2ascii [ options ]
	    [ inputfile [outputfile]]

DESCRIPTION

       The  Java  compiler  and  other	Java  tools  can  only process files that contain Latin-1 or Unicode-encoded (udddd notation) characters.
       native2ascii converts files that contain other character encoding into files containing Latin-1 or Unicode-encoded charaters.

       If outputfile is omitted, standard output is used for output.  In addition, if inputfile is omitted, standard input is used for input.

OPTIONS

       The following options are supported:

       -encoding encoding_name
	    Specifies the encoding name that is used by the conversion procedure.  The default encoding is taken from system property  file.encod-
	    ing.   The encoding_name string must be one taken from the first column of the table of supported encodings in the Supported Encodings
	    document:

	    http://java.sun.com/j2se/1.5/docs/guide/intl/encoding.doc.html

       -reverse
	    Performs the reverse operation: converts a file with Latin-1 or Unicode-encoded characters to one with native-encoded characters.

       -Joption       Pass option to the Java virtual machine, where option is one of the options described on the man page for the java  applica-
		      tion  launcher, java(1). For example, -J-Xms48m sets the startup memory to 48 megabytes. It is a common convention for -J to
		      pass options to the underlying virtual machine.
