Lets see: The output of "svmon" is in memory pages, which are 4k in AIX. The "size" and "inuse" values tell the physical memory and how of that is used. The machine has ~14GB memory installed (3.5 mio of 4k pages) and uses nearly all of it constantly. That the machine uses all of the physically installed memory is OK and to be expected.
The "virtual" column is the overall memory used by applications. The number is small compared to the number of installed memory and this means that the machine has enough memory for its day-to-day-operation. These figures are statistical in nature and this shows that your memory problems are short peaks of dramatically increased memory demand in a otherwise relatively idle machine.
The one java process you found is IMHO not the problem. If i interpret it correctly it is configured to use 256MB and this should be no big problem.
The output of "vmstat" shows nothing exceptional and the "lpstat" shows you have only 6GB of swap configured. This is a bit on the light side for 14GB of real memory, but otherwise only 1% of the swap is in use - it doesn't seem that you need more right now.
This leaves the question what goes wrong on your machine. You said you experience the problems only in very short timeframes. Start with searching the crontabs of all users you might find one (or several) troublemaker(s) which is (are) called only rarely. (I had such a situation once when a machine was experiencing a severe memory shortage with heavy paging activity every three days. We analyzed the situation and found out that a "mksysb" was responsible for the problem. We moved this mksysb-run to another time with less activity and the problem never happened again.)

vmstat
VMSTAT(1) BSD General Commands Manual VMSTAT(1)NAME
vmstat -- report virtual memory statistics
SYNOPSIS
vmstat [-CefHiLlmstUvW] [-c count] [-h hashname] [-M core] [-N system] [-u histname] [-w wait] [disks]
DESCRIPTION
vmstat reports certain kernel statistics kept about process, virtual memory, disk, trap, and CPU activity.
The options are as follows:
-C Report on kernel memory caches. Combine with the -m option to see information about memory pools that back the caches.
-c count Repeat the display count times. The first display is for the time since a reboot and each subsequent report is for the time
period since the last display. If no wait interval is specified, the default is 1 second.
-e Report the values of system event counters.
-f Report fork statistics.
-H Report all hash table statistics.
-h hashname Report hash table statistics for hashname.
-i Report the values of system interrupt counters.
-L List all the hashes supported for -h and -H.
-l List the UVM histories being maintained by the kernel.
-M core Extract values associated with the name list from the specified core instead of the default /dev/mem.
-m Report on the usage of kernel dynamic memory listed first by size of allocation and then by type of usage, followed by a list of
the kernel memory pools and their usage.
-N system Extract the name list from the specified system instead of the default /netbsd.
-s Display the contents of the uvmexp structure. This contains various paging event and memory status counters.
-t Display the contents of the vmtotal structure. This includes information about processes and virtual memory.
The process part shows the number of processes in the following states:
ru on the run queue
dw in disk I/O wait
pw waiting for paging
sl sleeping
The virtual memory section shows:
total-v Total virtual memory
active-v Active virtual memory in use
active-r Active real memory in use
vm-sh Shared virtual memory
avm-sh Active shared virtual memory
rm-sh Shared real memory
arm-sh Active shared real memory
free Free memory
All memory values are shown in number of pages.
-U Dump all UVM histories.
-u histname Dump the specified UVM history.
-v Print more verbose information. When used with the -i, -e, or -m options prints out all counters, not just those with non-zero
values.
-W Print more verbose information about kernel memory pools.
-w wait Pause wait seconds between each display. If no repeat count is specified, the default is infinity.
By default, vmstat displays the following information:
procs Information about the numbers of processes in various states.
r in run queue
b blocked for resources (i/o, paging, etc.)
memory Information about the usage of virtual and real memory. Virtual pages (reported in units of 1024 bytes) are considered active if
they belong to processes which are running or have run in the last 20 seconds.
avm active virtual pages
fre size of the free list
page Information about page faults and paging activity. These are averaged every five seconds, and given in units per second.
flt total page faults
re page reclaims (simulating reference bits)
pi pages paged in
po pages paged out
fr pages freed per second
sr pages scanned by clock algorithm, per-second
disks Disk transfers per second. Typically paging will be split across the available drives. The header of the field is the first charac-
ter of the disk name and the unit number. If more than four disk drives are configured in the system, vmstat displays only the first
four drives. To force vmstat to display specific drives, their names may be supplied on the command line.
faults Trap/interrupt rate averages per second over last 5 seconds.
in device interrupts per interval (including clock interrupts)
sy system calls per interval
cs CPU context switch rate (switches/interval)
cpu Breakdown of percentage usage of CPU time.
us user time for normal and low priority processes
sy system time
id CPU idle
FILES
/netbsd default kernel namelist
/dev/mem default memory file
EXAMPLES
The command ``vmstat -w 5'' will print what the system is doing every five seconds; this is a good choice of printing interval since this is
how often some of the statistics are sampled in the system. Others vary every second and running the output for a while will make it appar-
ent which are recomputed every second.

BUGS
The -c and -w options are only available with the default output.
The -l, -U, and -u options are useful only if the system was compiled with support for UVM history.
