zfs discuss - Mar 2008 - Java Web Console failures with ZFS Administration

We''ve got a couple of X4500''s. I am able to get into ZFS
Administration
on one of them, but on the newer one (latest Solaris 10 8/7 with
patches), which also has a larger number of ZFS filesystems, whenever I
go to the Java Web Console and click on ZFS Administration, after a
couple of minutes, it fails out with this error (from the server, not
the client, it appears):

Application Error

com.iplanet.jato.NavigationException: Exception encountered during
forward
Root cause = [java.lang.OutOfMemoryError: Java heap space]

 
I saw this in the list archives and attempted the suggested fix (stop
smcwebserver, clear tmp files, and restart it), to no avail:

Any suggestions?
 
thanks

In case anyone else is looking for a solution:

In /etc/webconsole/console/config.properties edited the java_options
line to:

java_options=-Xmx512m

To allow a heap size of up to 512MB.

And restart webconsole.

I am able (barely) to get into the ZFS Admin screen now... it''s still
nigh-useless, though, with 33k snapshots and 600-odd filesystems.
