Hi,

We are testing IBR-DTN in a vehicular testbed with On Board Units of limited resources and we have seen that IBR-DTN uses little CPU (around 2/3%) but a lot of virtual memory (from 84% to 140%, for instance). An example:

Mem: 45096K used, 16084K free, 0K shrd, 412K buff, 19996K cached

CPU: 2% usr 4% sys 0% nic 92% idle 0% io 0% irq 0% sirq

Load average: 0.15 0.12 0.13 2/87 21145

PID PPID USER STAT VSZ %VSZ %CPU COMMAND

1090 1 root S 61148 107% 2% dtnd -c /etc/ibrdtnd_rsu.conf

We have seen IBR-DTN (dtnd) use around 59MB of RAM from a total of 128MB, which is a lot for our devices. We are trying to mitigate this problem.

Do you have any idea of what might be causing IBR-DTN to use so much memory and if we can do something to reduce this usage, or is this just the way it goes and there's little or nothing we can do about it?

Thank you,

Romeu
