A 3rd Party Application has filled my Apex Flex Queue. Is there any way to clear this out? I'm unable to install other product updates. 

Any time we edit a contact in Not for Profit Starter Pack 3.0 we get the error: Apex trigger npsp.TDTM_Contact caused an unexpected exception, contact your administrator: npsp.TDTM_Contact: System.LimitException: Query of LOB fields caused heap usage to exceed limit.
We are using the Account Household configuration.

I am having issues with a managed Apex trigger from the NPSP.  This is the error I get anytime I try to update a contact: 

Error: Invalid Data. Review all error messages below to correct your data. Apex trigger npsp.TDTM_Contact caused an unexpected exception, contact your administrator: npsp.TDTM_Contact: System.LimitException: Query of LOB fields caused heap usage to exceed limit.

I am the system admin, but I am newer to Salesforce and have no background in development.  If someone could help me out with this error I would really appreciate it. I am not sure what happened to cause this. I have not changed any setup for weeks. 

Have a requirement to mass upload photo for the users like chatter photo. Is there a way to do it ?

Thanks in Advance!
