### 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 集群由3台服务器组成, seatunnel.engine.slot-service.slot-num=6,集群共18个slot资源. 当slot已占用6个时,并行提交两个需要6个slot的任务,此时可能导致并行提交的任务部分失败(非必现,概率中等)或全部失败(概率较小),日志记录apply resource not success, release all already applied resource 初步分析可能是并行提交时, 先查询并预分配了slot应分配的服务器, 但是在实际分配时,该服务器的slot可能已被其它并行任务全部占用,导致实际分配失败. ### SeaTunnel Version 2.3.5 ### SeaTunnel Config ```conf seatunnel: engine: classloader-cache-mode: true backup-count: 1 print-execution-info-interval: 120 print-job-metrics-info-interval: 10 queue-type: blockingqueue slot-service: dynamic-slot: false slot-num: 6 checkpoint: interval: 30000 timeout: 21474836460 max-concurrent: 10 tolerable-failure: 2 ``` ### Running Command ```shell -Dseatunnel.config=/alidata1/za-seatunnel/apache-seatunnel-2.3.5-SNAPSHOT/config/seatunnel.yaml -Dhazelcast.config=/alidata1/za-seatunnel/apache-seatunnel-2.3.5-SNAPSHOT/config/hazelcast.yaml -Dlog4j2.contextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector -Dlog4j2.configurationFile=/alidata1/za-seatunnel/apache-seatunnel-2.3.5-SNAPSHOT/config/log4j2.properties -Dseatunnel.logs.path=/alidata1/za-seatunnel/apache-seatunnel-2.3.5-SNAPSHOT/logs -Dseatunnel.logs.file_name=seatunnel-engine-server -Xms3g -Xmx3g -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp/seatunnel/dump/zeta-server -XX:MaxMetaspaceSize=1g -XX:+UseG1GC -XX:+PrintGCDetails -Xloggc:/alidata1/za-seatunnel/logs/gc.log -XX:+PrintGCDateStamps -XX:MaxGCPauseMillis=5000 -XX:InitiatingHeapOccupancyPercent=50 -XX:+UseStringDeduplication -XX:GCTimeRatio=4 -XX:G1ReservePercent=15 -XX:ConcGCThreads=2 -XX:G1HeapRegionSize=4M ``` ### Error Exception ```log apply resource not success, release all already applied resource ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### Screenshots _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
