Troubles with Transport Rule and AttachmentProcessingLimitExceeded predicate

Hi All

We have a lot of transport rules and one of them with predicate:

Name              : AttachmentProcessingLimitExceeded
LinkedDisplayText : when an attachment processing limit is exceeded<a id="AttachmentProcessingLimitExceeded"></a>

How co configure Limits for This Predicate or Transport for processing? ( We have a lot of messages with false positive )

P.S Exchange 2013 CU10
