After working flawlessley for a while, I'm suddenly getting a lot of errors in Phex. Every ten seconds or so I get the following error:

050908 00:02:43,0326 Error/Global:: (Global)! Exception occured: java.lang.UnsupportedOperationException
at phex.upload.UploadState.setTransferRateTimestamp(U nknown Source)
at phex.common.TransferRateService$SetTimestampTimer. run(Unknown Source)
at java.util.TimerThread.mainLoop(Unknown Source)
at java.util.TimerThread.run(Unknown Source)

Phex is also causing my PC to suddenly reboot without warning after running for a while.

My basic step:

3GHz CPU, 1 GB RAM
Windows XP Pro
Java 1.5.0_04-b05
Phex 2.6.4.89

1,473 files shared (34.13 GB)

I allow up to 20 parallel uploads, maximum upload bandwidth of 250 KB/s. Max 99 download connections, 99 downloads per file, 10 Mbps limit. javaw.exe usually uses around 100MB RAM, no significant CPU utilisation, but quite a lot of HDD access.

Any idea?

Cheers,
Fidel

Yes its a bug during upload caused from the old transfer rate calculation that was disabled (well obviously not fully

Since it is "the old" stuff it has no influence on anything else it just runs into a dead end and should not cause any other problems. Except dumping tons of text into your error log during uploads. But since its happening only every 10 seconds there should be no performance problems from it.

The fix for it is already in CVS.

System crashes are most likely not caused by Phex. Possible problems can come from faulty Java VM implementations, or most likely system driver or bus resource sharing problems.
Phex can put a high load on system devices like network card and disk drives. When I had some troubles with system crashes while using P2P, I found out that my network card, graphic card and disk controller shared the same IRQ and made the systems go crazy. Also removing all unnecessary USB devices can give a lot relieve on system resources.
Each USB device reserves system bus resources, so remove card readers, joysticks and these kind of things if you dont need them. Or if possible switch your USB device (printer, scanner) off.


Hope that helps.

Gregor, thanks for that. I have been getting IRQ issues, and my system has bluescreened ocassionally with an IRQ_NOT_LESS_THAN_OR_EQUAL message, so it looks like IRQ problems, or possibly driver issues. Oh what joy to fix!

Are there any known issues with J2SE 1.5 Update 4 on XP?

Cheers,
Fidel

Yes these problems are very hard to identify... all you can do is try to update drivers or try if you can find a better configuration.
You can also try to reduce the bandwidth use or the number of download connection. Maybe if you put a lower load on the system it might not crash that often.

I dont know any big Java 1.5 issues. To me it seems to be very stable.
