Warning. RPI 3, Mono 5.10.0.140 & preview VRS.

[zardoz]

Just a heads-up.

If you have a successfully running VRS instance on your Raspberry PI 3, don't upgrade your version of Mono from 5.8.0.127 to the latest in the Mono repository (5.10.0.140).

It has a very serious memory leak problem, resulting in my RPI3 rebooting every 9 hours.
Reverting to 5.8.0.127 restores stability.

I'm using this preview version of VRS.

Hey

I am running preview 04-FEB-2018 on a RPI 3 and Mono version 5.10.0.140. But I cannot confirm any reboots.

I tried to attach a memory usage graph to demonstrate the situation but the forum doesn't seem to like it in either Jpeg or Png.

That was the only change made, from 5.8 to 5.10 and back again.

I uploaded it to https://ibb.co/cHDLf7 instead.



5.10 update was done Frinday lunchtime and reverted Saturday evening.

As already mentoined I cannot confirm any reboots but I also experienced the memory leak.

There's this issue reported a couple of days ago in github for mono - looks like a possible culprit, VRS creates a lot of FileInfo objects when it's caching up aircraft photographs, silhouettes and operator flags:

That certainly sounds like a match.

I've certainly got all the silhouette and flag lookups active.

Mono 5.8.0.127 is absolutely rock solid.
