I am using Pega version 7.3.0 and facing one weird issue. Whenever I logs into system and launch tracer for first time, it works perfectly fine. When I close it and tries to run it for second time, Pega shows error "Cannot Launch Multiple Tracer Sessions for a requestor. This requestor is being traced by operator ABC(logged in requester)". This happens for complete tracer as well as tracing particular rule.
