Hi,
This is a Progress bug I reported three years before. Here is the answer from EMEA support:
Dear Gabor Topor:
This is a minor bug in that the process id should be an unsigned integer but we have it defined as signed. It does no harm but is is displayed incorrectly.
Please do not worry
Best Regards
