Why am I seeing this in my Activity Monitor? Is anyone else having this issue? This happens whenever I run iChat. Also, whenever I send pictures or files via iChat I get error messages when I try to continue chatting. I have to quit iChat and restart it in order to get chatting again.

any suggestions?

I have it all the time, but it doesn't crash my chatting

oh btw it is what keeps track of your contacts, try quitting it in activity monitor and watch your accounts go offline ;)

Sounds like you need to go on a bug hunt.... :( For a corrupted plist file, that is.

Try these (where . is the library in your user folder -- find | grep results, natch ;) ):


In particular -- try killing the iChatAgent, quitting iChat, and then moving the iChatAgent.plist file out of there and restarting. If nothing bad happens, or something good happens, delete the file you moved out of there.

Also try deleting the contents of the caches/ichat/ folder in your library.

I tried most of the above but it still comes back stalled everytime you restart iChat. A tad annoying but as far as I am aware it doesn't affect anything, so I've just chosen to ignore it.

These things seem to happen every now and then. Like that constant item that came up when repairing permissions under Panther, and the Library/Widget that needs repairing under Tiger.

Edit: A useful tool in hunting down corrupt .plist files is Preferential Treatment, which will do the terminal grunt work for you.
