I opened a Support ticked on 1/20/12, Looks like a SQE prob for me. I took out all my SQE's and distribution rule, and the MQE ran ok. But with the SQE's on, get same type errors. Further, the Application log of the SQE's give this error logged:
EVENT id: 11067
Application Warning: SQE RPC Interface : QES_AddWorkNext_NT4: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. Context Information: Patch Asssessment Error: hfnetchk6b.cab file is not properly signed. Call->BVNTQueryJobQueue::ConstructForLSD() - exception: (Domain: IND1, User: bvadmin, Source Computer: ahwappinind088.ind1.stvincent.org 10.170.8.141)
Exception was caught.
Hoping they can fix pretty soon, takes too long with only MQE performing query.
