As you can see above, Zn restarts running (managed) servers and tries to close open (worker) connections, swallowing any failures, and eventually cleaning up and recovering. Now, this is the normal behaviour, maybe something did change somewhere.

Wooh, it is getting weirder and weirder. I can open the image, start zinc, issue a request, shutdown zinc manually and save. The saved image I can reopen but then the keyboard is broken.

I'm not sure me saying "open and saving worked" was right. I cannot open any image that I have saved in the meantime. I only get a white window and no world.

Re: [Pharo-dev] How do diagnose image locks up (cpu 100%) on save?

by Norbert Hartl

strange but true I have a similar problem as of today. I don't have RFB installed I just installed zinc and use it. I can reproduce the behavior partially: Opening the image and saving works. Opening, starting a zinc server does as well. But opening, starting the zinc server and issue a request from a browser freezes the image when saving it. If I only issue one request from a browser the image freezes for something between half a minute and a minute. That smells like a timeout problem to me. The issue requested from the browser ends in "self halt" so there is an exception going on. I didn't switch zinc into debugMode for this. I wanted to get some more information in the loop by issuing a USR1 signal to the vm when it hangs. But in my case it does not write a dump file into my working directory. This should be assured behavior that whenever a USR1 signal is received by the vm that it always writes a file? I have plenty of space left on my device.
