My older MacBook Pro (snow leopard) freezes up every so often for 30 seconds.
There is not particular application that causes this, happens at random.
Console reveals nothing.
Tried resetting PRAM etc, running disk utility & defragmentation etc.
Drive has no bad sectors.
Using bootcamp & running windows there is no freezing at all.
Tried reinstalling OS.

This seems a well documented issue with no apparent solution.
Suggestions include disable virtual memory, disable bluetooth, disable sudden motion sensor etc - none seem to work.

If I boot using an external drive the system does not hang - this would usually indicate a problem with the internal drive (320GB - 140GB available).

Anyone here experienced this & know of a solution ?
 
I have a MacBook Pro 13" early 2011 version and I tried Snow Leopard on it a while back and it ran fine. However, that was only for a short while and then I changed back to Lion and then moved to Mountain Lion as soon as it was released. Maybe its worth considering moving to Mountain Lion if your MacBook Pro supports it.

Sounds like a hard drive issue to me. Weird that it doesn't affect bootcamp windows.

Spoke to digicape about it. They think it may be an issue within the mac partition of the drive which is why windows is not effected - which makes sense. However, i have run numerous hard drive utilities (mac and windows), all show the hard drive to be perfect.
 
Reformat / partition and install OSX..
Otherwise if you have Tech Tool Pro, give that a try and see if it picks up anything
 
Seemed to be related to or caused by java.
Removed all instances of java / java vm framework from system > library > java.
No more freezing.
 
Is the drive an SSD? Disabling trim is known to fix that if it is.

Ok... when you said freezing, I assumed total halt. I assume your mouse still worked at least?

The mouse / trackpad did work oddly enough

Aaah, understood. Yeah - when it's on the IO channel it's usually a solid freeze where the whole PC - including low level functions (Keyboard and mouse) don't respond.
We had one of those in our office - SSD used to halt for up to a minute and nothing responded until it came right.
 
Believe it or not, I had a problem with an Application called MoveLink (for the Suunto heartrate monitor). It also "froze" my MBP. Updated it and it works fine
 
I've been wondering why this sounded familiar and now I remember. I had similar issues on mine. Clean install revealed the culprit to be Adobe CS3. Upped to CS and now it behaves much better.
 
I had a similar problem but in my case it was the laptop freezing whenever a USB device came near it - in the end the culprit turned out to be Google's Android File Transfer app.
