This only happens to one contact, so it might be their fault. Either way I don't see how it is possible with WLM.
Many many times a minute their status changes from "Online" to "Idle" which I now have a 50mb (twice for my two emails) event log in the past 4 days (I deleted the event log file and disabled their emails from logging 4 days ago, I thought.) Since it the minimum time to go from "Online" to "Away/Idle" is one minute I think it
could be a Plus problem since it's Plus' logs and Plus' idle status.
Also I have disabled logging of that contact and their emails for at least four days and the logging continues. I have only six contacts on the second email so I know it is not because of sheer numbers of people changing their status normally.
You can see by the scroll bar that there is alot of text and it is almost exclusively that person.
The disabled event logs, unless I did something wrong. (I know you can not see the date that I changed it, but it was at least 4 days ago.
