It might be useful to add the datapoints to this report as comments so that they don't get lost.

also, the problem sounds similar to what Bert describes here: http:// lists.squeakfoundation.org/pipermail/squeak-dev/2006-August/107618.html

Hi Cedrick,

I've experienced similar problems with a 3.9 image and the 3.9-7 vm (mac and linux). I haven't had them for a while. I never found out why they occured, and they seemed to solve themselves after some time, if you let the image run. It could be a problem that gets solved once some objects get collected or something...

Hi

I'm using the 3.9 image, the developer version and I have the UI that freeze sometimes. Usually, when something like that appeared, I used <cmd> . to stop the process but here it's different. Whent the UI freeze, the cpu occupation is around 0% and <cmd> . just doesn't work !

Note, that when the UI is frozen but I can still use seaside applpication and sometimes I can get the hand back after playing with seaside or restarting a session.

Does someone encounter the same problem ?

I use 3.9g-7058 with most of the dev-packages I had this problem with linux (ubuntu), with vm 3.9-7 but also under windows.

Do you think this is a problem is due to my image ?

Thanks

Cédrick

I get something different. Squeak goes into an infinite loop, while this bug reports very low CPU usage.

In my case, Squeak eventually crashes and produces a stack trace involving CompiledMethod>>who and three other methods, infinitely recursing.

This is a 3.9 image and VM 3.9-7. But given the infinite recursion, it looks like an image-level bug.

for what it worth... in my case, when it happens on windows, I sometimes get a console with a message looping when the mouse is moving over the squeak screen:

WARNING: event buffer overflow

I'm not sure it's related to the same problem, as the console showed up (I think) after I hit <cmd> . several times...

Cédrick

ps: is there a console on the linux/unix vm ? and if yes how to show it

Hi

To solve, this issue (I often have), I have a workaround inspired by what Bert reported on a similar problem. I load RFB, and then if the UI freezes, I open the VNC controler application (http://localhost:8080/seaside/vnc) .Then supending and resuming the UI process from the seaside interface gives me the hand back in the squeak windows...

not nice, but better than loading changes ;)
