Computer freezes when media server connects to PS3

[spuik]

Ok this is what's up. When I start PS3 Media Server and let it search for renderers, it works as expected when my PS3 is powered off (meaning it doesn't find any renderers). If I turn on the PS3 after this, it still works as expected, the PS3 is found and streaming works.

If, however, the PS3 is powered on before I launch PS3MS, my whole computer freezes every time. It's always when the renderer is found. It searches for a while, then says it cannot find any renderers and displays the red cross. Then after a few seconds, it finds the PS3 and displays the green check symbol, and immediately the whole computer freezes so I have to reset the power.

I'm running Windows 7 64-bit. I recently upgraded to an SSD so I tried to reinstall to one of my old HDDs to see if that was the problem. It acted the exact same way. I also deleted the edited .bat that I used to launch PS3MS with and just tried a fresh install with no settings touched but it's always the same.

Again, if I only turn on the PS3 after the media server is already running, it works perfectly. Any ideas what's wrong?

Post a trace log - viewtopic.php?f=6&t=3507&start=30#p38484

Well, as you might expect, the problem is gone now that I'm trying to reproduce it... All I did was change the root level setting in logback.xml to TRACE. All's well that is well though so I'll post a log if the problem comes back. Thanks for helping.

All right, the freezing is back. This time it happened even though I turned my PS3 on only after the server was already running, so my theory on that is out the window. My trace log: http://pastebin.com/eufcrwUu (the server was on for three hours before I did anything).

e: here's another log http://pastebin.com/EAqSD9Fj with the same thing happening again

Anyone got any ideas?

Nothing untoward in the logs, and wouldn't expect a system resource issue since it's just at the connection.
Maybe have a system level java issue? Try doing a full java purge and install - viewtopic.php?f=6&t=3507&start=30#p41214
Also maybe a NIC driver issue. Try a driver update.

Nope, didn't help after all. I was using java7 update7 when this started and now I've uninstalled it and installed update9. It worked a couple of times but then same thing. I removed it and tried update9 32bit version, which didn't work at all. Then I removed that and reinstalled update9 after which it worked once but then same thing again. Now it won't work even once after remove and reinstall.

I also updated the LAN driver for my motherboard, after which it again worked for one time but froze up on the second launch.

I'm at a loss.
