hi Feng Are you using the open jdk or the oracle jdk?

hi Feng, Thanks for your reply, we are 8 u192 JDK, may be is the question, I found a JDK issue:https://bugs.openjdk.org/browse/JDK-8215355.

Re: After using the jemalloc memory allocator for a period of time, checkpoint timeout occurs and tasks are stuck
hi Rui, Which version of JDK are you using? This issue could potentially be a bug in the JDK version. If you are using JDK 8, you can try using OpenJDK 8u265 as a possible solution.

Re: After using the jemalloc memory allocator for a period of time, checkpoint timeout occurs and tasks are stuck
hi rui, In general, checkpoint timeouts are typically associated with the job's processing performance. When using jemalloc, performance degradation is generally not observed. It is advisable to analyze whether the job's garbage collection (GC) has become more frequent.

After using the jemalloc memory allocator for a period of time, checkpoint timeout occurs and tasks are stuck
After using the jemalloc memory allocator for a period of time, checkpoint timeout occurs and tasks are stuck. Who has encountered this? flink version:1.13.2, jiemalloc version: 5.3.0
