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

Hi,
what synthesizer are you using?
I found no synthesizer in the list of processes running.
When orca freezes, try to kill speech-dispatcher, using killall speech-dispatcher.

Hi, and thanks for the quick response.

Yes, I can see that mint-update is running as a process under my
username. I didn't think it was much different from update-notifier, so
I didn't give it much of a thought. On Ubuntu, update-notifier runs in
the background and puts an icon in the notification area when updates
become available. Mint-update appears at first glance to do the same
thing. I did notice, however, that if I activate the mint-update icon
when it's in my notification panel, Orca hangs completely, and only a
reboot can solve the problem. I also didn't consider mint-update to be
the potential cause of the problem, since it appears to be running all
the time, even when Orca is responsive. However, it's possible that it's
calling something else that hangs Orca or the at-spi or something else
entirely.

I also am including here the process line for mint-update, in case it
can help. This was read from ps during a time that Orca was unresponsive.

/usr/lib/linuxmint/mintUpdate/mintUpdate.py

Very shortly after I took this reading, I restarted orca and it came
back to life with no difficulty until the next time. Also, Here's the
output of the uptime and ps commands that Trever recommended, which I
also received during a period of unresponsiveness:

It's interesting to note that Thunderbird seems to be using a lot of CPU
at the moment this snapshot was taken, but Thunderbird isn't running
most of the time when I have this problem. It's also interesting to note
that at-spi-registryd and not Thunderbird is using quite a lot of memory
at this same moment. Funny thing is that mint-update doesn't seem to
factor into this equation at all according to ps.

I hope I was able to help a little, so I know where to file a bug report
and what to include in it. Sometimes, these things seem pretty hard to
track down.
