Description

When running the cross-language test suites () Flink fails on TestXLang_Multi with the following error:

19:29:14 2021/08/27 02:29:14  (): java.io.IOException: Insufficient number of network buffers: required 17, but only 16 available. The total number of network buffers is currently set to 2048 of 32768 bytes each. You can increase this number by setting the configuration keys 'taskmanager.memory.network.fraction', 'taskmanager.memory.network.min', and 'taskmanager.memory.network.max'.
19:29:14 2021/08/27 02:29:14 Job state: FAILED
19:29:14 --- FAIL: TestXLang_Multi (6.26s)

This doesn't seem to be a parallelism problem (go test is run with "-p 1" as expected) and is only happening on this specific test.
