Error while confirming document

Hello,

I need help with an error message relatef to hornetq that we detected  in one of our prod environments. The related package has 5 documents, 4 documents were successfully signed and the last one signing confirmation failed and produced this error.

I appreciate any information to understand the problem. 

There are not similar error message in previous or next days.

Thanks,

Mónica
