Hi ,
There could be multiple causes for your issue. Please have a look at the following article from Kevin Holman:
The most common issues causing the 31552 events seen are:- A sudden flood (or excessive sustained amounts) of data to the warehouse that is causing aggregations to fail moving forward.- The Exchange 2010 MP is imported into an environment with lots of statechanges happening.- Excessively large ManagedEntityProperty tables causing maintenance to fail because it cannot be parsed quickly enough in the time allotted.- Too many tables joined in a view or query (>256 tables) when using SQL 2005 as the DB Engine- Poor SQL performance issues (typically disk I/O latency)- Using SQL standard edition, you might see these randomly at night, during maintenance as online indexing is not supported using SQL standard edition.- Messed up SQL permissions- Too much data in the warehouse staging tables which was not processed due to an issue and is now too much to be processed at one time.- Random 31552’s caused my DBA maintenance, backup operations, etc..
