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.

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.

On Mon,
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
