Let me quote this and put it in code tags so the columns line up and I can read it.

[edit] Argh, I can't, copy-pasting ruins the spacing and I can't even quote you to get it, it just vanishes completely because you put it in quote instead of code tags. Could you repost in code tags?

That 2396 in cache counts as free memory by the way, don't be alarmed because of the low count in 'free'.

Yes, Java is using 20% of available memory. The important column is RSS, for "resident set size", which only counts memory actually in RAM and physically in use.

Sometimes there's complications like lots of shared libraries artificially inflating the memory count(imagine a 10MB shared library used in 100 processes, which'd total a gig, even though it's using the same ten megs of physical RAM for all of them) but this isn't one of them.

vboxbeep

vboxbeep(1)						    Linux System Administration 					       vboxbeep(1)

NAME

       vboxbeep - isdn voice box (beeper)

SYNOPSIS

       vboxbeep [OPTION] [OPTION] [...]

DESCRIPTION

       vboxbeep is a daemon, that watches several message directories. If new messages are found it will beep. Vboxbeep does not use vboxd, it can
       only watch local directories.

       Vboxbeep is also used to stop this annoying beep.

OPTIONS

       Without any options, vboxbeep will signal an already running vboxbeep to stop its beep. Only root can start it as daemon.

       -s, --sound HOURS
	      Hours to play beep signal. Use 24 hour format, like 0-23. Multiple hours can be given separated by commas, a "*" is used for always,
	      "-" for never.

       -m, --messagebox DIR
	      Message directory to scan. You can use this option several times.

       -p, --pause SECS
	      Time to wait between every check. Default is 5 seconds.

       -k, --kill
	      Kill a running vboxbeep. This option can only be used by root.

       -h, --help
	      Show summary of options.

       -v, --version
	      Show version of program.

NOTE

       vboxbeep  will  only work if it is installed suid root. This may be a security hole, so many distributions do not install it suid root, and
       thus it's useless. If you want to enable vboxbeep, please read the distribution-specific documentation how to do  that  (e.g.  with  debian
       gnu/linux read /usr/doc/isdnutils/README.debian).
