Pentium 3.0Ghz hyperthreading 1GB RAM, 1.5GB swap, using wired but have wireless adaptor installed as well.
Ubuntu 8.04 was fine. Did an upgrade to 8.10, and had this runaway NetworkManager problem. There were other issues related to a problematic upgrade, so I wiped hdd and installed a clean 8.10, which fixed the other issues but the NetworkManager (v0.7) problem reoccurred. Upon bootup NetworkManager process starts consuming memory, confirmed in System Monitor. Within 15-60 minutes it has consumed 600-800MB slowing the system to a crawl and eventually Ubuntu stops responding. Executing "sudo killall NetworkManager" before this point clears the consumed memory and returns the system to a stable ~200MB memory. Executing "sudo NetworkManager" causes the runaway memory problem to begin again. Below is some output of /var/log/syslog when the NetworkManager process is running.
