You can consider cleaning the log directories and/or increasing disk space.
Directories that be considered for clean up:
For details on how to increase disk space if you are on the Adobe Commerce on cloud infrastructure Starter plan architecture, see Increase disk space for Integration environment on cloud in our support knowledge base. The same instructions can be used for increasing the space of the Adobe Commerce on cloud infrastructure Pro plan architecture Integration environment. For Pro Production/Staging, you need to file a ticket to Adobe Commerce Support and request increased disk space. But typically, you will not have to deal with this on the Staging/Production of the Pro plan as Adobe Commerce monitors these parameters for you and alerts and/or takes actions according to the contract.
