New mongodb 3.2.x version (3.2.21) was recently released, and I’ve built new packages for ubuntu 18.04.
Also I’ve spotted that previous packages of version 3.2.20 have some annoying behaviour, meaning mongodb server starts to occupy cpu 100% after some time doing useless “usleep” loops (pretty much doing nothing waking up several times a second to do nothing again).
I don’t know with what this is related, but this time to build packages I’ve gathered all the knowledge around the internet how to do that additionally to my researches. There are few more tricks included building those packages now including some armhf specific compiler and linker options and I don’t see that strange behaviour anymore. If you had problems with packages from the previous post, – upgrade. If you just stumbled upon this post – install 3.2.21, it is better.
