Hi Paul, A likely scenario is that you have a process in an endless loop (probably the one in ByteString(String)>>encodeOn:). Its stack grows and uses more and more memory. The first thing to try is control-. (or apple-.), which should interrupt the current process. If the GUI is still responsive you can also open the process browser (in the Tools menu) and try to debug or just terminate the offending process.

Hi -
I have done something to my image and don't know how to fix it. When it opens it maximizes one of the processors and allocates a large amount of RAM to itself. When I attempt to run the Debug > Start profiling all Processes it crashes the vm after I move the mouse to the top of the screen. When I run
Process allInstancesDo: [ :p | | rules | rules := ProcessBrowser nameAndRulesFor: p. rules second ifTrue: [ p terminate ] "1=name, 2=safe-to-kill, 3=safe-to-debug" ].
from here: http://wiki.squeak.org/squeak/1799 nothing changes.
Printing 'ProcessBrowser new processList' in a workspace gives:
a WeakArray(a Process in Delay class>>handleTimerEvent a Process in SystemDictionary>>lowSpaceWatcher a Process in [] in Delay>>wait a Process in WeakArray class>>finalizationProcess a Process in nil a Process in ByteString(String)>>encodeOn: a Process in [] in BlockClosure>>newProcess)
And the VM statistics are:
uptime 0h8m53s memory 1,055,051,120 bytes old 1,050,497,028 bytes (99.6%) young 83,708 bytes (0.0%) used 1,050,580,736 bytes (99.6%) free 4,470,384 bytes (0.4%) GCs 4,999 (107ms between GCs) full 3 totalling 18,400ms (3.0% uptime), avg 6133.0ms incr 4996 totalling 120,999ms (23.0% uptime), avg 24.0ms tenures 112 (avg 44 GCs/tenure)
Are there other things I can do to get it back under control or should I just save everything in some MC repositories and set up a new image? I'm reluctant to do that now because I don't know what I did to create the situation I'm in.
Thanks for your help
Paul
