Damn copy and paste..... I've re-edited for the missing details below,
my apologies.
Quoting Justin Spies <[EMAIL PROTECTED]>:
...
The VSIZE question--when the JVM starts, it places a hold on the
memory it thinks is needed. So if you allocate a maximum heap of
256MB + the permanent size of 128MB (which I realize you haven't set
and I don't recall the default) + extra overhead memory =3D3D 469MB of
VSIZE. Note that the JVM needs memory, as Chris mentioned, of HEAP +
PERMSIZE + (THREADMEMORY * NUM THREADS).
To check memory usage, you'll want to add the following to your
startup parameters (plus any others you want):
-verbose:gc -Xloggc:/tmp/garbage.log -XX:+PrintGCTimeStamps -XX:PrintGCDetai=
=3D
ls
The above should read
-verbose:gc -Xloggc:/tmp/garbage.log -XX:+PrintGCTimeStamps -XX:PrintGCDetails
...
Also note that the above instance is using much more REAL memory
(88MB) than the first instance, but has much less total allocated
memory (288MB). It's highly likely that the application is defaulting
to a heap size of something like or 9MB.
The above should read
... to a heap size of something like 64MB or 96MB...
