Infinite loop creating new page due to page header overflow.

[pk1109]

We have a situation where we have a number of reports that have been running fine for years, all of a sudden starts throwing exception. We are on WebSpeher 9.x, Java 8, JasperReport 6.5.1. I'm not sure about the sequence of events but at some point it seems like the jasper engine gets corrupted (or doesn't clean itself up) and starts throwing the execption. These reports works fine otherwise with the same data once we restart the server.

Hi, does any one have any suggestion where to start looking? We are at a point that we have tried everything from upgrading jasper library to 6.7 to adding governor check but something is causing it to throw infinite loop exception and once it happens it does it on every report. 

Thanks!
