Has anyone come across this issue before? When googling I'm seeing issues with SQL server 2012 and deadlocking in the SSISDB which were resolved in a service pack but not seeing many issues with SQL 2014.I have two packages stored in the Integration catalog which execute at the same time.This is causing a deadlock on [internal].[execution_parameter_values] in the SSISDBThe work around is to set one to execute slightly later but was just wondering if anyone had seen this issue in 2014 or if there was something about how I have set up my SSIS projects/packages which might be causing the issue.Deadlock xml is below[code="xml"]<deadlock> <victim-list> <victimProcess id="process1bc8da4e8" /> </victim-list> <process-list> <process id="process1bc8da4e8" taskpriority="0" logused="0" waitresource="KEY: 7:72057594042843136 (267401a7be15)" waittime="438" ownerId="49357173" transactionname="user_transaction" lasttranstarted="2016-06-08T16:00:03.460" XDES="0xc5a183b0" lockMode="X" schedulerid="4" kpid="22012" status="suspended" spid="61" sbid="0" ecid="0" priority="0" trancount="2" lastbatchstarted="2016-06-08T16:00:03.390" lastbatchcompleted="2016-06-08T16:00:03.387" lastattention="1900-01-01T00:00:00.387" clientapp=".Net SqlClient Data Provider" hostname="CAHQX-PRDSQL01" hostpid="2320" loginname="S-1-9-3-2870711563-1196531925-3037930163-1186165430" isolationlevel="serializable (4)" xactid="49357173" currentdb="7" lockTimeout="4294967295" clientoption1="673185824" clientoption2="128056"> <executionStack> <frame procname="SSISDB.catalog.set_execution_parameter_value" line="235" stmtstart="15918" stmtend="16512" sqlhandle="0x0300070058e0ef6aaefd350180a4000001000000000000000000000000000000000000000000000000000000">UPDATE [internal].[execution_parameter_values] SET [runtime_override] = 1, [value_set] = 1, [base_data_type] = @parameter_type, [parameter_value] = @parameter_value WHERE [execution_parameter_id] = @execution_parameter_i </frame> </executionStack> <inputbuf>Proc [Database Id = 7 Object Id = 1794105432] </inputbuf> </process> <process id="process2da3ad468" taskpriority="0" logused="0" waitresource="KEY: 7:72057594042843136 (f6d22cb28365)" waittime="438" ownerId="49357169" transactionname="user_transaction" lasttranstarted="2016-06-08T16:00:03.457" XDES="0x311a34d10" lockMode="X" schedulerid="4" kpid="24356" status="suspended" spid="63" sbid="0" ecid="0" priority="0" trancount="2" lastbatchstarted="2016-06-08T16:00:03.390" lastbatchcompleted="2016-06-08T16:00:03.347" lastattention="1900-01-01T00:00:00.347" clientapp=".Net SqlClient Data Provider" hostname="CAHQX-PRDSQL01" hostpid="21396" loginname="S-1-9-3-2870711563-1196531925-3037930163-1186165430" isolationlevel="serializable (4)" xactid="49357169" currentdb="7" lockTimeout="4294967295" clientoption1="673185824" clientoption2="128056"> <executionStack> <frame procname="SSISDB.catalog.set_execution_parameter_value" line="235" stmtstart="15918" stmtend="16512" sqlhandle="0x0300070058e0ef6aaefd350180a4000001000000000000000000000000000000000000000000000000000000">UPDATE [internal].[execution_parameter_values] SET [runtime_override] = 1, [value_set] = 1, [base_data_type] = @parameter_type, [parameter_value] = @parameter_value WHERE [execution_parameter_id] = @execution_parameter_i </frame> </executionStack> <inputbuf>Proc [Database Id = 7 Object Id = 1794105432] </inputbuf> </process> </process-list> <resource-list> <keylock hobtid="72057594042843136" dbid="7" objectname="SSISDB.internal.execution_parameter_values" indexname="PK_Execution_Parameter_value" id="lock1ebdc9680" mode="RangeS-S" associatedObjectId="72057594042843136"> <owner-list> <owner id="process2da3ad468" mode="RangeS-S" /> </owner-list> <waiter-list> <waiter id="process1bc8da4e8" mode="X" requestType="convert" /> </waiter-list> </keylock> <keylock hobtid="72057594042843136" dbid="7" objectname="SSISDB.internal.execution_parameter_values" indexname="PK_Execution_Parameter_value" id="lockee56d300" mode="RangeS-S" associatedObjectId="72057594042843136"> <owner-list> <owner id="process1bc8da4e8" mode="RangeS-S" /> </owner-list> <waiter-list> <waiter id="process2da3ad468" mode="X" requestType="convert" /> </waiter-list> </keylock> </resource-list></deadlock>[/code]
