(now posted as a separate question) I've got the following problem on my MacMini with OS X 10.3.9. and tried a lot of things (permissions, harddisk repair, PRAM reset, Startobjects remove...) nothing worked...
After a while after login (sometimes seconds, sometimes minutes, but seriously always after a while), usually reproducible when starting "large" programs like Adobe Photoshop after a few seconds, the mouse and screen update rate sink immediatly to once in 5 to 10 seconds and all processes are slowed down similarly. No work is possible afterwards, not even killing some processes or restarting the mac by key-stroke.
I used "top" from the beginning and could see (after a few minutes of "not-refressing") a lot of DMProxy (with UID 0) processes (100-1000) blocking my systems, when this issue has occured.
I even don't know which process has started these DMProxy's, so this posting is my last help, before reinitializing the whole system - I still don't know, how this could happen.
Any suggestions - how to get rid of this DMProxy's
Best Regards, Rico
