Full Discussion: "too big" and "not enough memory" errors in shell script
Operating Systems AIX "too big" and "not enough memory" errors in shell script Post 302284905 by bakunin on Friday 6th of February 2009 01:15:08 PM

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.

freemind

FREEMIND(1)						      General Commands Manual						       FREEMIND(1)

NAME

       freemind -- A Java program for creating and viewing mindmaps.

SYNOPSIS

       freemind [no_options]

DESCRIPTION

       This manual page documents briefly the freemind command.

       This  manual  page was written for the Debian distribution because the original program does not have a manual page.  Instead, it has docu-
       mentation as a mindmap (see Help menu in FreeMind).

       freemind is a program that allows to create and view so-called mindmaps, as well as export them to HTML or  different  image  formats.	It
       also has a plugin concept to extend its functionality.

OPTIONS

       This program does not have any option. Just start it!

ENVIRONMENT VARIABLES

       DEBUG	 If   this  environment  variable  is set, freemind gives more information on how it finds its different elements, as well as some
		 other information.

       JAVACMD	 Default value for the java virtual machine (the java command).

       JAVA_BINDIR
		 If $JAVACMD is not set, the java virtual machine is searched under $JAVA_BINDIR/java.

       JAVA_HOME If $JAVACMD and $JAVA_BINDIR are not set, the java virtual machine is searched under $JAVA_HOME/bin/java.

       PATH	 If all $JAVA... environment variables fail, the java virtual machine command (java) is searched in the $PATH (with which).

       CLASSPATH	ADD_JARS
		 The $CLASSPATH variable also lets one specify additional jars, which is good, if you want to add a new Look&Feel jar  (the  motif
		 one is so ugly...). Alternatively, the content of $ADD_JARS will be prepended to $CLASSPATH.

       FREEMIND_BASE_DIR
		 Directory where FreeMind searches for its plugins and libraries

FILES

       /etc/freemind/freemindrc        ~/.freemind/freemindrc
		 freemind  tries to read its environment variables from /etc/freemind/freemindrc and ~/.freemind/freemindrc, so that specific set-
		 tings are possible at machine and user level.

       /usr/bin/java
		 If all searches through environment variables fail, the java virtual machine is expected to be /usr/bin/java;	if  not,  freemind
		 exits with an error.
