Unable to assign multiple jobs when running infer inside docker

[phnx]

I'm using infer in a customized docker container (Ubuntu 20.04). Infer was installed from the latest release.

$ infer --version
Infer version v1.1.0

The capture command below works fine.

 infer capture -- make

However, when I start the analysis without specifying the job number. I receive following errors.

$ infer analyze

The only workaround is to explicitly specify #job = 1, which will take longer time to run.

$ infer analyze -j 1

I think this has something to do with the number of available CPU cores inside docker. But I couldn't find that information in the document. Appreciate all suggestions.
