Hi,
Within our QA environment we have a scenario which is occasionally being slow to return a response to the sender. Within the trace there is a section:
<Trace level="2" type="Timestamp">2015-01-19T18:02:49Z CET Message Level Security for Request (outbound)</Trace>
<Trace level="1" type="B" name="CL_XMS_PLSRV_IE_ADAPTER-CALL_XMS_HTTP">

</Trace>
</Trace>

As you can see it starts this section of the trace at 18:02:49 but doesn't finish until 18:04:22.
My question is what could possibly be making this section take so long. Usually it runs straight through with barely a difference in the clock from start to end. However, sometimes it does the above. Is there anyone out there expert enough in PI traces/architecture to say what the above section relates to and why it might be going so slowly.
Cheers,
