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.

lp-shell

lp-shell(1)						      General Commands Manual						       lp-shell(1)

NAME

       lp-shell - Open an interactive launchpadlib shell.

SYNOPSIS

       lp-shell [-a] [-cPROGRAM] [--python] [--ipython] [service] [LP API version]

DESCRIPTION

       lp-shell opens an interactive Python shell with a launchpadlib.Launchpad object "lp" which is ready for use.

       It  authenticates against Launchpad with the consumer name "udt-lp-shell". When using lp-shell with the -a option it will use the anonymous
       login from launchpadlib.Launchpad.

       By default lp-shell connects to the "production" Launchpad service using the "1.0" LP API version.

       If you want to connect to another Launchpad service, call lp-shell with the service name as the second argument. lp-shell supports all ser-
       vices known by launchpadlib Python module.  Currently known are (list can be incomplete or outdated): "production", "staging", "dogfood".

       A  different  LP  API version can be selected by passing the API version to use as the third argument. Current supported are: "beta", "1.0"
       and "devel".

OPTIONS

       -a     Login anonymously into Launchpad.

       -c PROGRAM
	      Don't enter a shell but only run the specified Python program and exit.

       --ipython
	      Use an ipython shell if available (default).

       --python
	      Use a regular python shell.
