Hi All,
Latley i have been facing this issue of event id 2115 in my SCOM management console popping up frequently, which basically shows delay in DBW writes.
On the SQL end i found that below qurey is the major contributer for blocking:

I know exchange mp is always a pain, but how to trouble shoot and fix it ?
TIA,
