It is very difficult to diagnose this type of problem without more detailed data. It seems like those experiencing the problems are primarly on Windows. Data such as which task is hogging the CPU, how many page faults are occuring, and by which task, etc. would be invaluable. Without that data, I'm going to play a hunch. I don't know if this issue has been resolve for you folks or not, but this behaviour seems very much like something I've seen with particularly agressive virus scanners such as Kaspersky and a couple of others. I might be way off base with this diagnosis in this case, but the information below might be useful for others in the future if I've misdiagnosed in this case. The reports here don't seem to indicate which tasks are actually hogging the CPU times, causing large numbers of page faults, doing large quantities of I/O, etc. This would be key information. Large VMs don't mean very much, as that's not the same as increasing consumption of memory, which does matter (ie. leak). Some virus scanners when set on more agressive modes perform a checksum on each file, and store that checksum and other information in an additional "stream" of the file. The goal is that the virus scanner can compare the checksum information in its database with that in the new stream of the file more quickly than re-performing the checksum itself (esp. for large files). For database files that change constantly (ie. slims music database), and tagged music files, this agressive virus scanning performs horribly, and the system spends all its time doing disk I/O and checksum calculations, leaving nothing for other apps. The result, users experience long hangs or stalls, and the system is unusable. Reducing the agressiveness of these scanners helps resolve the problem with no loss of security. For those of you who don't know how to see this information, you can add many more very useful pieces of data to your Windows task manager. Under the Processes tab, open View->Select Columns and add all the possible columns. For your Performance tab, be sure to enable View->Show kernel times as well. During the times when the system seems wedged, watch and sort by the columns that show most activity. -- MrC _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
