Hello Team,

we are planning to upgrade Nexus to 3.43.0 but we are getting out of memory (java heap) even if we have set basic memory requirement , but I can see in official dockerfile it has been set to 2703MB  
, [docker-nexus3/Dockerfile at 3.43.0 · sonatype/docker-nexus3 · GitHub](https://github.com/sonatype/docker-nexus3/blob/3.43.0/Dockerfile#L87)

so what is recommended memory for Nexus, I can see system requirement but want to know if there is specific memory is recommended for docker container since we are using Debian as base image.

PS: we are using nexus as docker .

Please guide.

Regards,  
SAM
