Memory usage monitoring?

Hi *,

I've a box running Solaris 10 6/06. 5GB of physical memory + 5GB of swap.
The box is running 3 zones and a zfs volume delegated to zones.

The server is up since 2 days and, today, 3GB of RAM were allocated in +/- 30 minutes. Then, no more big allocations.
(my SNMP monitoring and smc console reported the same values)

If I run a 'prstat -Z', I get:

ZONEID NPROC SIZE RSS MEMORY TIME CPU ZONE
     2 36 657M 524M 10% 0:03:24 0.6% app5
     0 59 447M 232M 4.5% 0:03:55 0.1% global
     7 30 111M 69M 1.3% 0:00:41 0.0% delta5
     6 37 172M 95M 1.8% 0:00:35 0.0% web5

          Total: 1377M

How can I debug this issue? Memory leak? Is there new "buffers" allocated by the kernel? Help!

Regards,
Xavier
