Summary | 0007498: In Sq 9885 on Ubuntu doing Beeper beep latches the cpu usage to 100% | |||||||||||
Description |
This is a strange one. I have several images and vms on my machine. I use the gnome lauchers to launch them directly and the -plugin option to point to a plugin directory The 4.1 release cadidate 2 (sq 9885) is launched with 'myDir/bin/squeak' -plugins 'myDir/lib/squeak/3.11.3-2135' '/home/hubuntu/Sq9885b.image' using the 3.11.3-2135 vm as indicated by the distribution. That said once lauched the cpu usage is normal until the first time I use sound. In a fresh sq 9885 Open a workspace. Type "Beeper beep" Doit. Note the sound plays. But after I do that once: The cpu monitor indicates the squeakvm is hogging the cpu usage (>90%) along with the pulseaudio Next type alt-. (i.e. stop interupt.) Cpu usage goes back to normal. |

Additional Information |
I have tried the test in my 3.9 squeak with the older vm and this does not happen there. I have tried it with a sq 9926 (3.11 updated) using pharo-vm-0.15.1b-linux and a Alsa plugin from the etoys distro. I can get the sound w/o the cpu latch up. So this seems tied to the vm and plugings in 3.11.3-2135 vm distribution. It seems to involve locking up the sound resource. Other programs trying to use sound sometimes seem to go haywire after squeak has triped the condition. Does this happen on other system configurations? Does it happen if the release candidate is run with other vm's? Are there other vm's for linux for this distribution other than the one I found? Yours in curiosity and service, --Jerome Peace |
