Hi,

What causes the JDS to become so sluggish, specially when moving between
virtual desktops after a couple of weeks heavy use?

The tools running is Firefox, Thunderbird OpenOffice acrobat
reader(alot) and emacs shells.

Then I use remote X sessions aswell alot.

I am running S10 u7 SunRay on AMD

Something (most likely Firefox) has eaten up all the RAM.

prstat -s rss

Will show you. Leaks from graphical application often show up under Xorg.

My current OpenSolaris session has been up for 23 days without slowdown.
Newer versions of Firefox and cousins are much less prone to leek memory:

Firefox and Thunderbird (in some versions at least) seem to continuously
grow, and may have reached the point where they are larger than the
memory available, causing them and everything else to swap. Exiting them
and restarting them can solve that. Use prstat to see if you have anything
else which is big which you can either shutdown, or might similarly try
restarting and see if it frees up lots of memory.

To both of you ofcourse.

It feels like when apps been page-outed, but vmstat shows 2 GB RAM
available.
