This seems reasonable, but I find myself wondering whether something more like the memory high watermark code would be useful even in non-excessive situations. In case you aren't familiar with it, that code logs whenever the amount of memory OVS is using doubles relative to the last reported value. That means that you get at most a small number of log messages (since you can't double the amount of memory very many times before running out) but it's easy to look at the logs and spot, within a factor of 2, how much memory OVS was using. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
