Torrent Software Crash
I have had Transmission 1.4 crash on me several times.

It originally happened when I was using uTorrent beta so I figured it was just an unreliable build no big deal. Deleted all torrent data and started fresh w/ transmission. Again, fails. Deleted that data because I thought it was of the fact that I was d/l to my external. Reloaded again and boom, crashes. So I logged out and restarted (w/o reloading torrents) we are running strong for the past...3 minutes.

Any ideas? It seems to really bog down my computers performance too. (not the internet but the actual me doing things.

Does it freeze, crash to desktop or restart?

It sounds like a memory issue.

I was a bit baffled by my issue as I didn't think that downloading torrents with transmission would be related to a memory problem. I opened Activity Monitor/System Memory tab and started up my torrents. I watch the memory usage and noticed that It would slowly start filling available memory. The system would consistently freeze when I passed 3.6GB. I then opened a large document in Photoshop and did some heavy work with it and was able to replicate the freeze.

Test to see if this is the problem.

Use the boot-flag
Code:
maxmem=2048
on startup. This will limit the memory that OSX uses to 2GB. Run your torrents as usual and see if you still get the freezes.

-The fix
Slashack over on insanely mac posted some modified 64bit kexts which fixed the problem for me. We are not using the same chipset so you will have to see if one of his works for you. http://forum.insanelymac.com/index.php?showtopic=127611

-Using maxmem as a fix
Try the maxmem flag on boot and if it works add it to com.apple.Boot.plist (located in /Library/Preferences/SystemConfiguration/) The syntax goes something like this:
Code:
<key>Kernel Flags</key>
<string>maxmem=****</string>
Replacing **** with the amount of memory to use. Many people have reported 3456 (3.38gb) works well. I have pushed mine to 3584 (3.5gb) and have not been able to make it freeze.

Network related freezes
Most of the time people with your symptoms have the problem with memory. I have heard others who have had issues with their lan drivers. Id use maxmem to test for the above first.

i'm currently using 4.8gb of my ram and there is no freeze...I have 8gb of ram. I could try opening up some fcp and some adobe suite and see if that pushes me to any where near 8gb. What is the "stock" maxmem input?

There is no stock value. For most Ive seen, it seems to start giving problem around 3.2-3.5GB.

Id just open up Activity Monitor's Memory tab and compile some video... maybe open every program in your apps folder and see how high you can push it. I had a hard time getting up to 4GB. Ill have to do some research on an app that will simulate this. I am sure there is something out there.

So as of now at 4.8GB your stable?

I have not had a chance to do any extensive editing in FCP on my AMD rig. Has it worked well for you in terms of performance? I use a PPC dual 2.4Ghz Proc & 4GB of memory at work and from the little I have done on my AMD rig it seems my rig outperforms. I have been pretty impressed so far.

Absolutley amazing. I'm pretty sure I'm using the same computer at my work as you are and my Quad Phenom and the 8gb of ram is incredible. I run the whole FC Studio and it runs amazing on here. I haven't had one issue with a freeze or lock up while in FC. Just amazing.

Let me backup a bit. Are you using maxmem or those modified 64bit kexts? Or have you corrected the freezing issue some other way?
