Comment 17 for bug 182923

I also get the problem, and I mostly get it after suspend. Not always, but often. As far as I remember, I've always had it since I first started to use MN 1.5 years ago, and I've had it on all the Ubuntu versions I've installed in the course of the time. I now also have it on a new computer with a fresh Ubuntu 8.04 64bit installation. I currently have 4 IMAP, 1 mbox, and 1 Gmail account monitored by it.

My impression is that the high CPU usage occurs NOT when the network connection is unequivocally down, but while network manager is acquiring a connection, or in one of these in-between states where there is a connection, but it is stale. In my university, for instance, the wireless network is open, but you only get out through a vpn server. If I connect to the network but not to the vpn, that's a pretty sure bet to get MN to race I believe. I don't have it close, though, to try it out. Or some routers which let you connect but don't serve you because of an access list restriction.

Thanks a lot, Jean-Yves, for this very useful program!
