"blued" (bluetooth) process takes up more than 1 GB of RAM

Lately I've noticed that choosing "suspend activity" in Apple menu) takes about one minute instead of a few seconds to put my computer to sleep. I've launched Activity Monitor to try to see what the computer is doing, but did not find anything obviously wrong. I was a bit surprised to have only a little bit of my 4 GB of RAM free, especially that I had only a few apps open, not particularly memory-hungry.
Upon waking the Mac, I noticed that the first item on Activity Monitor was "blued", using 1,03 GB of "real memory" and 1.46 GB of virtual memory. All I have been able to find about this process is that it is the "Bluetooth daemon". It seems to be an excessive memory footprint for a daemon using only 0 to 0.03% of CPU. At work I have a bluetooth mouse and keyboard. At home I have another bluetooth mouse.

Any suggestion? Possibility of a memory leak?

Anybody else finds putting their mac to sleep takes longer than under Leopard?

Thanks in advance,

Denis

I'd be worried if both of those were higher values. For the system to go thru polling various processes and making sure nothing is happening/pending isn't going to occur in a few seconds and BT is just another reason for it to take a bit before the tent is properly folded.

Hi K T,

Finally I don't think the high memory footprint of blued causes the long delay in going to sleep. I killed the blued process, which 24 h later still uses a minuscule 2.4 MB of real RAM and 29.0 MB of virtual memory. But putting the mac to sleep is still slow.

I conclude 2 things:

Something has gone terribly wrong for the blued process to grow from 2.4 MB to over 1000 MB of memory.

Snow Leopard is faster than Leopard for most things, but surprisingly putting the Mac to sleep is not one of them.

Both these conclusions are weird!

try is deleting your bluetooth preference files - there could be a problem with the new 'blued' daemon using your old 10.4 preferences if you just upgraded (or archived and installed) to 10.5.

I'd suggest trashing:

/Library/Preferences/com.apple.bluetooth.plist

...and then looking in:

~/Library/Preferences/

for anything 'com.apple.bluetooth'. ('~' means your home folder).

After you do that, try a restart and see what happens.
