---------------------------------
Summary: Limit netty threads used in PubSubDUnitTest
Key: GEODE-8503
URL: https://issues.apache.org/jira/browse/GEODE-8503
Project: Geode
Issue Type: Test
Components: redis
Reporter: Jens Deppe
The {{PubSubDUnitTest}} currently fails when run under stress
({{StressNewTest}} job in CI). There are various factors at play here:
- Test hosts have 96 vCPUs and netty will use 2x this number for each
EventLoopGroup (of which we have 2). For some tests we end up needing almost
1600 threads which seems excessive.
- VMs are not recycled between every test run but thread resources are also not
cleaned up synchronously between runs; this seems to be the biggest problem.
