分表 INSERT 操作偶尔报错 返回

向Postgresql数据库分表持续插入数据, 每次批量插入200条数据:

var snowflakeIdList = this.dbClient

    .Insertable(this.trackDataRecordsForInsert)

    .SplitTable()

    .ExecuteReturnSnowflakeIdList();

开始工作正常, 但是不定时(一到两个小时后)突然会开始报错:

NpgsqlTransaction

Exception: System.ObjectDisposedException

Message: NpgsqlTransaction

StackTrace:

   at Npgsql.ThrowHelper.ThrowObjectDisposedException(String objectName, Exception innerException)

   at Npgsql.NpgsqlTransaction.CheckReady()

   at Npgsql.NpgsqlTransaction.Rollback(Boolean async, CancellationToken cancellationToken)

   at Npgsql.NpgsqlTransaction.Rollback()

   at SqlSugar.AdoProvider.RollbackTran()

   at SqlSugar.SplitInsertable`1.ExecuteReturnSnowflakeIdList()

然后开始持续报错: 

Transaction is already completed

Exception: System.InvalidOperationException

Message: Transaction is already completed

StackTrace:

   at SqlSugar.AdoProvider.ExecuteCommand(String sql, SugarParameter[] parameters)

   at SqlSugar.InsertableProvider`1.ExecuteCommand()

   at SqlSugar.InsertableProvider`1.ExecuteReturnSnowflakeIdList()

   at SqlSugar.SplitInsertable`1._ExecuteReturnSnowflakeIdList()

   at SqlSugar.SplitInsertable`1.ExecuteReturnSnowflakeIdList()

一旦开始报错就停不下来
