OutOfMemoryError: GC overhead limit exceeded during autobuild #2604
Comments
Can you give an example of a project where you're seeing this OOM condition? |
Having tried this locally, I find the max memory pressure from that job is around 3.5GB, which should be achievable on a standard GHA runner. Have you tried the gradle.properties fix suggested? |
Yeah i have tried. But it seems wierd, because I have another project which using more memory, but I did not needed to make any fix as this error suggested. This project using less memory I needed to set 4 gb memory then it ran successfully. Is that something you will look at ? Or.. ? |
Because our current Kotlin extractor runs as a plugin to the Kotlin compiler which is itself managed by Gradle, unfortunately for now we need such memory-usage matters to be addressed at a higher level that isn't in our direct control. We anticipate in the future Kotlin extraction will likely use a different process model at which point we will have greater control over our own operating environment; however, for now I'm afraid it will occasionally be necessary to give Gradle more memory. |
Steps to Reproduce:
Trigger the autobuild process.
Observe the build failure due to OutOfMemoryError.
Expected Behavior:
The build should complete successfully without running out of memory.
Actual Behavior:
The build fails with an OutOfMemoryError.
Suggested Fix:
Increase the memory allocation for the Kotlin daemon in gradle.properties:
kotlin.daemon.jvmargs=-Xmx<size>
Environment:
Kotlin version: 2.0.21
Gradle version: 8.11
Java version: 21
