jv16 PowerTools 2006 hangs
I hit the hang condition again. Perhaps these observations on my notebook will help find the cause:
1. I let PT run for about two hours
2. TaskSwitch.exe (a Microsoft Power Toy) showed two jv16pt.exe tasks
2a. When I switched to one, the main window had focus,
but clicking on it only produced the windows "not responding" sound
2b. When I switched to the other, the main window did not have focus,
and clicking on it also produced the windows "not responding" sound
3. Process explorer nt and task manager showed PT using 5 to 20% of the
single cpu for about two minutes
4. Then PT spiked to 60 to 100% for a few seconds --
this pattern continued every two minutes for the whole two hours
5. During each spike, PT accessed a subdirectory in the Backups folder --
it was not the same one each time
6. Sometimes, a PT access to BackupPruning.dat was also visible during the spike
7. PT had about ten active threads the whole two hours
8. PT could be ended with a "Close" on the taskbar
9. All this suggests PT was in an interruptible loop, perhaps in the BackupPruning function
10. When PT was restarted, all was fine.
