Our team investigated that this is normally associated with a huge app size being developed. This happens because the builder hub bursts its memory due to many files on the app. Delays in linking the app may also be associated with this issue

Try using vtex link on an app with a huge size or a lot of files. You may receive the following errors:

11:51:13.298 - error: Workerpool Worker terminated Unexpectedly exitCode: null signalCode: SIGABRT workerpool.script: /usr/local/data/service/src/node/utils/workers/worker.js spawnArgs: /usr/local/bin/node,/usr/local/data/service/src/node/utils/workers/worker.js spawnfile: /usr/local/bin/node stdout: null stderr: null vtex.builder-hub@0.299.0 11:51:13.299 - error: App build failed with message: Workerpool Worker terminated Unexpectedly exitCode: null signalCode: SIGABRT workerpool.script: /usr/local/data/service/src/node/utils/workers/worker.js spawnArgs: /usr/local/bin/node,/usr/local/data/service/src/node/utils/workers/worker.js spawnfile: /usr/local/bin/node stdout: null stderr: null

13:30:05.456 - error: App ended with exit code 15. Will restart in 10s. service-node@6.38.3

Analyze the size of the app and its files, if it is necessary try to divide the app into smaller apps so the size will be reduced.
