Our Java builds (based on maven) had started to error for no obvious reason.
The first time it happened it WAS obvious - the log was too big. So I decreased its verbosity.
Now it fails on timeout. EXCEPT: the tests usually takes ~20 minutes. Now, after the 20 minutes (or so), the build continues for another 25-30 minutes, idle, showing (repeatedly every 30 seconds) messages like this:

You can see an example log: https://travis-ci.org/github/applitools/eyes.sdk.java3/builds/678044021
And the rest of the builds: https://travis-ci.org/github/applitools/eyes.sdk.java3/builds
