Report error - javax.imageio.IIOException: Error reading PNG metadata

Report error - javax.imageio.IIOException: Error reading PNG metadata

Hi
 
The first time I run a report I get no error and the report outputs correctly however if i then go to run another report or the same one i get the 'javax.imageio.IIOException: Error reading PNG metadata ' error.    If i go and restart the SDP-MSP service i can successfully run the report but then any subsequent reports will give the 'javax.imageio.IIOException: Error reading PNG metadata ' error again.
 
Many thanks,
 
Matt
