[drone-kubernetes-runner] Pods being evicted due to load on ephemeral-storage resource

We have a rather complex build pipeline (made a of several stages, many of them running in parallel) and we are observing how kubernetes is evicting the pods with the following error message:

Status:       Failed
Reason:       Evicted
Message:      The node was low on resource: ephemeral-storage. Container drone-dy9knlkacntta6nww0em was using 76Ki, which exceeds its request of 0. Container drone-6znzow12d6jgizlmu5qw was using 72Ki, which exceeds its request of 0. Container drone-mgqlm8uy2jmnabwax1me was using 68Ki, which exceeds its request of 0.

Is this something that you have seen before and if so, is there a way to workaround it? We are using Kubernetes 1.19, created in Azure via AKS.
