Storing build cache on osx exceeded 10 minute timeout

4.5G of ccache regularly times out in OSX builds only on the storing cache stage.

Famous error:
“No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.”

Or maybe its hitting the 50 minute build limit that’s triggering this error. It seems odd that it should always timeout in this exact spot however.

However this from travis’ internal scripts and not the config fie or its scripts.

All other builds in them matrix of similar size compete quicker:
s390x 204s

x86_64 bionic - 166 seconds

I’m experimenting cutting this side down, however I don’t think a cache storage failure at the end of the build couldn’t cause it to error.

Other suggestions welcome.
