MartijnVisser opened a new pull request, #29822:
URL: https://github.com/apache/flink/pull/29822
## What is the purpose of the change
The heavy deployment end-to-end test fails on the Azure Java 11 nightlies
(10 of 198 runs since 2026-08-01) with OutOfMemoryError: Metaspace. Its
TaskManagers reach about 64 MiB of committed metaspace, which is the limit the
test sets.
## Brief change log
- Raise `taskmanager.memory.jvm-metaspace.size` from 64m to 96m
- Raise `taskmanager.memory.process.size` from 1024m to 1056m, so the heap
stays at 440 MiB
## Verifying this change
This change is already covered by existing tests, such as the heavy
deployment end-to-end test itself. Locally on Java 11 (x86_64 under emulation,
2 CPUs) the TaskManagers peak at 61-64 MiB committed metaspace both with 64m
and with 96m, and the heap stays at 440 MiB. The failure does not reproduce
locally, so the nightlies will tell.
