W-dragan opened a new issue, #6745: URL: https://github.com/apache/seatunnel/issues/6745
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened When I run batch CDC on a k8s container using version 2.3.5, from MySQL to PG, there are occasional JVM errors that occur twice a month, causing the program to exit incorrectly and then restart. The JDK version I used has not changed. Interestingly, I did not encounter this issue before using versions 2.3.2 and earlier. I suspect that this issue is related to three factors: 1. The JDK version, which was also used before. 2 uses a new version of seasunnel. 3. Multiple CDC tasks are from MySQL to PG. Previously, PG. was not supported ### SeaTunnel Version 2.3.5 ### SeaTunnel Config ```conf - ``` ### Running Command ```shell - ``` ### Error Exception ```log 2024-04-13 21:22:19,238 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - wait checkpoint completed: 10271 2024-04-13 21:22:19,315 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - pending checkpoint(56111/13@829166127863955457) notify finished! 2024-04-13 21:22:19,315 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - start notify checkpoint completed, job id: 829166127863955457, pipeline id: 13, checkpoint id:56111 2024-04-13 21:22:19,319 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - pending checkpoint(10271/8@831088865526677505) notify finished! 2024-04-13 21:22:19,319 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - start notify checkpoint completed, job id: 831088865526677505, pipeline id: 8, checkpoint id:10271 2024-04-13 21:22:19,350 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - wait checkpoint completed: 56111 2024-04-13 21:22:19,355 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - wait checkpoint completed: 56111 2024-04-13 21:22:19,428 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - pending checkpoint(56111/6@829166127864020993) notify finished! 2024-04-13 21:22:19,428 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - start notify checkpoint completed, job id: 829166127864020993, pipeline id: 6, checkpoint id:56111 2024-04-13 21:22:19,431 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - pending checkpoint(56111/5@829166127864020993) notify finished! 2024-04-13 21:22:19,431 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - start notify checkpoint completed, job id: 829166127864020993, pipeline id: 5, checkpoint id:56111 2024-04-13 21:22:19,529 INFO org.apache.seatunnel.engine.server.checkpoint.CheckpointCoordinator - wait checkpoint completed: 10195 2024-04-13 21:22:19,560 INFO org.apache.seatunnel.engine.server.CoordinatorService - [172.25.193.222]:5801 [seatunnel] [5.1] *********************************************** CoordinatorService Thread Pool Status *********************************************** activeCount : 10 corePoolSize : 0 maximumPoolSize : 2147483647 poolSize : 24 completedTaskCount : 16323369 taskCount : 16323379 *********************************************** # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f1d2525ab7c, pid=8, tid=0x00007f1d2177c700 # # JRE version: OpenJDK Runtime Environment (8.0_212-b04) (build 1.8.0_212-b04) # Java VM: OpenJDK 64-Bit Server VM (25.212-b04 mixed mode linux-amd64 compressed oops) # Problematic frame: # [thread 139763073967872 also had an error] C [libc.so.6+0x85b7c] cfree+0x1c # # Core dump written.
