I am running UDmonitor in order to cache work units on a machine
that is on a dial up connection. Every now and then the UDmonitor program window will go blank - all the controls, buttons tabs etc. will dissapear and when passing the mouse pointer over the window it will turn into an hourglass. If the Udmonitor was minimized, clicking on its icon in the system tray will not bring its window to visibility. The WCG agent will show a certain percentage of the task completed but this will never increase. The animation of the protein or HIV protease docking continues and the clock indicating time spent on the task will continue to increment. I have left the machine running in this state for over 2days but the percentage completed does not increase. If I close the agent then the UDmonitor and restart UDMonitor and the WCG agent the calculation continues(percentage completed starts to increment) - unless UDmonitor freezes again. In the task manager the percentage activity for UDmon is very high, 95%-99%, while AUtodock is about 3%. When everything appears to be working these percentages are reversed. I have another machine running UDmon and have not experienced this problem with it. What is going on? |

Hi finiduck,
the percentage activity for UDmon is very high, 95%-99%, while AUtodock is about 3% Well, that's not right. I have no specific idea what is going wrong. All I can suggest is to uninstall UD Monitor and run some diagnostics from the 'Useful Utilities' thread at http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=2490 such as: 1) Motherboard Monitor: http://mbm.livewiredev.com/ Monitors CPU temperature. If the manufacturer does not supply a temperature monitoring program for your board, then see if this program works with your computer. If the temperature is too high, then read http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=2683 2) CPU Tester: http://7byte.com/index.php?page=download General diagnostic program 3) Memory Tester: http://www.memtest86.com/ Memory diagnostic program If these do not identify a problem, then reinstall UD Monitor and see if the new installation works. In other words, I am puzzled. Anybody have any better ideas? mycrofth |

I wonder whether UDMonitor is trying to log a checkpoint or switch a workunit slot, and it can't. The workunit is going to stop and wait at that point. Something else may be hogging the computer, and UDMonitor doesn't have enough memory available to do its thing.
----------------------------------------In the task manager the percentage activity for UDmon is very high, 95%-99%, while AUtodock is about 3%. When everything appears to be working these percentages are reversed. That would imply that nothing else is running though.How much memory is on that machine? How long has it been since the machine was rebooted? Something in the system could also be becoming unstable. I do not see that problem here. You don't have to uninstall UDMonitor. Just end it. It is possible to exit UDMonitor completely and let the current workunit run in the current slot. You might do that to make sure that the time and percentages are incrementing in the workunit. If not --- there is a problem with the workunit, not UDMonitor. If the workunit finishes before UDMonitor is restarted, it will simply want to call in and get replaced. You can restart UDMonitor anytime you want and it will pick up with the current situation and ignore the checkpoints and/or callins between. If it is running the newest workunit, at that point after restarting, I will tell it to run the oldest workunit. If it has been replaced, it will go to find the oldest slot and run that. I often do that on a slow Pentium III/500. I have 4 slots, but run the current one with UDMonitor out of the picture. After the callin and the workunit is replace, I'll bring UDMonitor back up and ask it to run the oldest slot. After the switch, I'll exit UDMonitor again and leave it off. That computer only calls in every couple of days anyway.

This is a fast (2.4Ghz) machine with 512 MB RAM.
The problem happens in the middle of a WU being processed, not during switching slots. Most of the time UDmon operates correctly - switching to a new slot after completing a WU. If I exit the WCG agent and then terminate UD Monitor and then restart the UDmon and agent, the WU will continue from the % completed when I stopped them and will correctly increment a few % points before UD Monitor freezes again. I have to terminate the UDMonitor from the task manager, clicking on the X(close window) does nothing. Also what is puzzling is the UD Monitor window goes blank - all windows controls dissapear. I will try some of the utilities you mentioned as I am operating UD monitor on another machine with no problems - even though both machines are identical in specs. Thanks for your assistance. |

This is a fast (2.4Ghz) machine with 512 MB RAM. Also what is puzzling is the UD Monitor window goes blank - all windows controls dissapear. I have seen it go blank on a Compaq AMD64 3400+ 2.4GHz and freeze the machine when I hit two UDMonitor buttons in succession when the first action had not finished. The blanking was because the graphics for the UDMonitor box was not redrawing. I will try some of the utilities you mentioned as I am operating UD monitor on another machine with no problems - even though both machines are identical in specs. I could fix it by exiting UDMonitor with the task manager (as you have done) and restarting UDMonitor. In the meantime, I got another 1 Gb of memory for it, which helped a lot. The machine seems smoother now with 1.5 Gb. 512 Mb could be a little tight if running Win XP. We will wait for the results of your utility run. Memtest86+ helped to identify some bad memory. It took three tries to get a good brand of the 1 Gb that would work with the original 512 Mb. Memory can be sneaky that way, and the speed of the memory should be matched. In the middle of the workunit ... UDMonitor will log the checkpoint, so will be doing something at that time. HPF: a checkpoint will be taken when the detail percentage jumps. Some jump after every pass. I have seen some slow folders take over 15 passes left to right before the percentage goes up. FA@H: a checkpoint will be taken when the green line ends and starts over.
