Forest0923 opened a new pull request, #19961: URL: https://github.com/apache/kafka/pull/19961
https://issues.apache.org/jira/browse/KAFKA-19390 The AbstractIndex.resize() method does not release the old memory map for both index and time index files. In some cases, Mixed GC may not run for a long time, which can cause the broker to crash when the vm.max_map_count limit is reached. The root cause is that safeForceUnmap() is not being called on Linux within resize(), so we have changed the code to unmap old mmap on all operating systems. The same problem was reported in [KAFKA-7442](https://issues.apache.org/jira/browse/KAFKA-7442), but the PR submitted at that time did not acquire all necessary locks around the mmap accesses and was closed without fixing the issue. -- This is an automated message from the Apache Git Service.
