Symptoms

The prstat command is run during the web server startup and this is what it shows:

1) Before the server is completely started:

$  prstat
  PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP
 <PID> <USER>    391M  133M cpu13    0    0   0:00:14 1.7% webservd/38

2) After the server is completely started:

Prstat ran during instance startup
$  prstat
  PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP
 <PID> <USER>   1240M 1034M sleep   59    0   0:00:28 2.6% webservd/109

Prstat ran after instance startup
$  prstat
  PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP
 <PID> <USER>   1240M 1034M sleep   59    0   0:00:28 0.2% webservd/109

As you can see, the process size has reached about 1.2G and this is much higher than 400M/500M normally seen in a freshly started 64bit web server.
