logging to memory disable
please help
I am a little bit puzzled by this. We see some graphs which show memory usage ramping up and rapidly unloading, but nothing detailing any actual behaviour problem with the device. And we have a set of rules for logging [some of which appear to have been disabled and replaced with other rules] rather than any logging.
So, @sinchist could you elaborate on what the problem is that you are seeing and your interpretation of the information you have posted? Then we might be able to help.
I guess that memory consumption drop tightly correlates with device reboots. And I guess that @sinchist is afraid that without rebooting, memory consumption would keep increasing until OOM condition which would result in ROS reboot (which is more or less the same as controlled reboots ... but not exactly the same).
But then I don't see a problem with ROS using up most of available RAM with time, it's exactly the way normal linux kernel on normal linux machine would behave (although it would max out RAM consumption much faster due to highly variable workloads compared to ROS which runs the same set of services the whole time). But the curve does seem to flatten slightly before those drops ... and considerably below maximum (RB2011UiAS seems to have 128MB RAM).
For comparison: RAM usage on my RBD52G with 256MB RAM, recently running 7.19.6. It's only for routing, no wireless driver even installed.
One can see more or less steady increase in RAM consumed with occasional faster increase ... which ends up in a constant consumption after a short while. So far I haven't encounter any problem regarding RAM consumption ... it could be it's due to occasional reboot (due to ROS upgrade).
FWIW, About 25% of my production routers are experiencing memory leaks after updating to v7.20.1 in October. These include CRS109, CRS112, CCR2004, and HEx routers. The CRS109/112 routers max out on RAM after ~28 days and then reboot. The CCR2004 show a steady increase in RAM usage, but will not max out for many months yet. There is no apparent pattern as to why some routers have the leak and others do not. Notes for the 7.20.7 release say a memory problem related to logging was addressed. I will likely do some test deployments using that version.
CRS109 router:
CCR2004 router:
I can confirm that v7.20.7 fixes the issue on the effected routers.
