Over the last few days, my frontend stopped building with these errors:
#11 213.7 [73:0x702d870] 141768 ms: Scavenge 1588.0 (1979.6) -> 1586.3 (1995.6) MB, 9.4 / 0.0 ms (average mu = 0.781, current mu = 0.343) allocation failure;

To resolve this, I had to increase Node's max-old-space-size by adding an environment setting to my frontend/Dockerfile.
# syntax=docker/dockerfile:1
ARG VOLTO_VERSION=17.15.2
FROM plone/frontend-builder:${VOLTO_VERSION} as builder
ENV NODE_OPTIONS="--max-old-space-size=8192"
