network-manager consumes 70% CPU and WLAN gets slow

[kiu]

Binary package hint: network-manager

up-to-date gutsy

After several days of nonstop usage (no suspend/hibernate in between) of the same WPAII WLAN, the NetworkManager eats 40-70% of CPU and the network gets slow.

i think this bug is fixed in the network manager currently available in -proposed. You can enable that archive in System -> Administration -> Software Sources.

If you still see the bug after upgrading to 0.6.5-0ubuntu16.7.10.0 let me know.

aeh ... let me know by reopening this bug.

Thanks,

Still happens on my machine. I am not sure but its maybe only consuming the CPU after i hibernated.

Thanks for your report, can you test the same with Hardy Heron and let us know how it goes? thanks.

I see the same issue with Hardy. I didn't think to check CPU usage but, after a day or two of uptime including a few suspend/resumes, pinging my router with my wireless card configured with networkmanager takes over 1 second instead of a few milliseconds. When I kill nm-applet and the root networkmanager processes and run dhclient, performance returns to normal.

i dont see this bug anymore. neither in hardy nor intrepid.
