[Box-Admins] Slowness of source.squeak.org

Ken, thank you so much.  The cause of the slowness we've been seeing the
last few days is some runaway seaside client Process.  It was busy
rendering HTML on the difference between two different versions of
45Deprecated-fbs.8 (with two different UUID's) but, somehow, had itself
caught in an endless loop that was sucking resources and causing the image
to grow.

I downloaded the image to my local machine, terminated the rogue process
from the Process Browser, reuploaded it, renamed the old
Squeak3.11-8824-SS.image to .bad, then killed the SS process.

At first, it looked like daemontools was restarting it, but something
looked weird when I grepped for the process; there were two of them.

chrismuller at box2:/home/squeaksource$ ps -ef | grep Squeak3.11-8824-SS.image

*root      2218  2109  0 Sep13 ?        00:00:01 readproctitle service

-plugins /usr/local/lib/squeak/3.11.3-2135 -vm-display-none

And yet, I could not access source.squeak.org.

So, I killed both of those and waited for daemontools to start it again.  I
thought it would be immediate, but repeated ps checks did not show
anything.  Maybe I didn't wait long enough, but I went ahead and started it

So source.squeak.org is up but now there are two processes, each owned by
root, instead of squeaksource.  Hmph.

root      5753 26447  0 21:45 pts/0    00:00:00 sudo
/usr/local/lib/squeak/3.11.3-2135/squeakvm -pathenc UTF-8 -encoding UTF-8
-plugins /usr/local/lib/squeak/3.11.3-2135 -vm-display-none
root      5754  5753 15 21:45 pts/0    00:00:12
/usr/local/lib/squeak/3.11.3-2135/squeakvm -pathenc UTF-8 -encoding UTF-8
-plugins /usr/local/lib/squeak/3.11.3-2135 -vm-display-none

I don't know why daemontools didn't start it automatically, but as I was
sitting there, waiting for it, I realized how much I dislike not being in
control of whether the process is running or not...

Any advice?
