Re: [orca-list] Orca becomes unresponsive periodically on Linux Mint 9

Hi,

ok, looks like two processes are dead locking to me, and although I
haven't taken a really careful look to see what is non standard I
really suspect mint-update so try taking it out of the equation and
see what happens.

I thought I'd go ahead and take a new snapshot of my processes and
cpu/memory usage during the next unresponsive period without
Thunderbird running just to see what would happen. The results are
quite baffling at this point.

Of course, this means that nothing is maxing out CPU or memory while
Orca is unresponsive. Nothing is taking more than 10.3% of either
during this time, but for some reason, orca or at-spi or something
else is behaving as though it doesn't have enough CPU time to
perform its function. I'm truly at a loss now, and hope someone can
still help.
