> When running the cross-language test suites () Flink fails on TestXLang_Multi
> with the following error:
> {noformat}
> 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){noformat}
> 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.
