I think you have a memory leak, how long have you been monitoring ?
Are any processes core dumping ? Check errpt ...

it may be due to your maxperm / minperm settings and is just normal
growth of backing store for working (computational) memory pages.

please paste the output to the following commands when the system is
under load.

vmstat 1 10
/usr/samples/kernel/vmtune
/usr/samples/kernel/vmtune -a
