Solution
You can consider cleaning the log directories and/or increasing disk space.
Directories that be considered for clean up:
var/logvar/reportvar/debug/var
For details on how increase disk space if you on the Starter plan, see Increase disk space for Integration environment on Cloud. The same instructions can be used for increasing space of Pro plan Integration environment.
For Pro Production/Staging, you need to file a ticket to Magento Support and request increase disk space. But typically, you will not have to deal with this on Staging/Production of the Pro plan, because Magento monitors these parameters for you, and alerts and/or takes actions, according to the contract.
