Hi,
I am running Network manager version 0.9.4.0 on Ubuntu, and I see
that my syslog is flooded with the messages shown below:

What can be the possible cause of these messages? What is the best
approach to debug this? Any suggestions will be appreciated.
Hi Alok, I don't know, looks like NetworkManager runs out of memory. Does the process use a lot of memory? What gives `ps aux` as RSS? Do you have any problems beside warnings in the logfile? Sorry to say this, but 0.9.4 is quite old and no longer actively supported upstream. So not sure what help you will find here. Thomas
