Error: Unable to display Flowtrace due to exception while initializing obj

Question

Hi All,
we are unable to open Flow Trace for bpel processes in em console. we are using SOA11.1.1.5.
this issue is intermittent and occurs only on heavy load.
in the console we are getting error as:
Exception occured while retrieving the Flowtrace XML for the Composite Instance; ECID: 6c3ce42605336b8c:-2ae055b0:136da4fdf05:-8000-0000000000003890
