Empty fields in MWS Services log

Hi all,

I have a problem where some fields in the MWS Service Log (Monitoring/Integration/Services) appears empty only when I invoke the pub.prt.log:logActivityMessages service. The fields are populated correctly in the search results list but if I click to see details of any message the field “Custom Context ID” is empty and the “Duration” field wrongly displays “0d 00:00:00.000”. If I disable the logActivityMessage service invokation in the service the fields are populated correctly in the log.

Running webMethods 8.2 sp2

Any ideas what might cause this?
