Try adding the thread name to your conversion to ensure it is a different
thread
<conversionPattern value="%level %date{yyyy-MM-dd'T'HH:mm:ss.fffzzz
<http://opengrok.factset.com/source/s?path=ss.fffzzz&project=/platform/wauds/mainline>}
%property{hostname} [%thread] %property{guid} %message%newline" />
It seems more likely that a thread is being reused.
