  • I have searched the issues of this repository and believe that this is not a duplicate.

Ⅰ. Issue Description

使用Seata时，SAGA模式。一个接口比如创建订单，前一个创建订单请求，由于特殊场景（比如在扣库存请求失败时库存服务重启，或者处理事务时服务重启）导致事务处理失败。后面的创建订单请求，无法正常进行事务处理，会提示状态机实例表（seata_state_machine_inst）主键冲突。理论上，一个新的请求，应该有一个全新的全局事务id（xid）,为何会出现此问题？

Ⅱ. Describe what happened

If there is an exception, please attach the exception trace:

Record statemachine start error: [10000] [Unknown error] [Internal error], StateMachine: CreateOrder, XID: 172.23.0.244:8091:524592202459856896, Reason: Duplicate entry '172.23.0.244:8091:524592202459856896' for key 'seata_state_machine_inst.PRIMARY'

Ⅲ. Describe what you expected to happen

提示上面的错误，是使用seata时，使用了相同的全局事务id。导致了插入数据库表：seata_state_machine_inst，提示主键冲突。期望应该不会出现生成重复的全局事务id，能正常进行分布式事务处理。

Ⅳ. How to reproduce it (as minimally and precisely as possible)

Minimal yet complete reproducer code (or URL to code):

Ⅴ. Anything else we need to know?

希望可以解释一下出现这种问题的原因，在不升级seata版本的前提下，能够修复或者避免出现此类情况。

Ⅵ. Environment:

  • JDK version(e.g. java -version ): 1.8
  • Seata client/server version: 1.4.1
  • Database version: mysql 8.0.25
  • OS(e.g. uname -a ): Linux 4.19.91-26.al7.x86_64
  • Others:

方便提供下异常堆栈吗？
Is it convenient to provide the exception stack?

数据库里有了相同id的全局事务记录了，是上一个事务执行失败的记录。目前状态是RU状态。

因为配置了重试30分钟如果不成功就失败，所以也没有在重试了

是这个对吗？

Are you set DbStateMachineConfig#seqGenerator gen seq by bussinessId? If seqGeneraor is set, it needs to be unique even if it is the same businessId.

NO，I have not set DbStateMachineConfig#seqGenerator , and debug find the DbStateMachineConfig#seqGenerator value is null after I set。

And StateMachineEngine object show the DbStateMachineConfig#seqGenerator value like this:

This should be default value
