Bug [Command Line][CI] Unity compiler is sometimes stucked during CI

Hello,
we have a really annoying issue in our automation pipeline. During some build unity stucks when he must compile element in scriptassemblies library.
I will post some picture to illustrate the issue it will be easier than many words :


As you can see on the left side it's the stuck job log, preloading is the last entry and unity doesn't go further. On the right side it's a successful job and as you can see, it continues until the end.

So currently in our gitlab CI, the job generates this :


Does any unity devs ( for example @superpig ) could have any idea or hints to help me to debug this ? Cause currently I don't know what I can really do to investigate on this and find what could we do to generate (or solve) this ?

 

Sorry @superpig , I didn't see your answer yesterday
So, we are on :
- Unity 2018.4.0f1
- Mac OS Mojave 10.14.4

When the job stucks it can be on Android or iOS platform target.
I didn't check on Standalone cause we did them only somtimes.

If you need more information, feel free to ask

 

The latest version is 2018.4.3f1 - maybe try updating and seeing if that fixes it?
