Q:

SQL Server SPID is sleeping or runnable but nothing happens for over an hour

I use SQL Server 2012 BI edition.
I've executed two SQL Agent Jobs that run SSIS packages. Historically, the jobs have been running absolutely fine. Today, the jobs just stopped/hanged just before completing step 1 out of 4.
I've run sp_who2 and nothing is blocking anything. What can I do to "awake" my jobs? Details of sp_who2:

Status   sleeping                      
BlkBy      . 
Command  AWAITING COMMAND 
CPUTime  131276 
DiskIO   607734
LastBatch    01/12/2017 15:55

The jobs have not failed yet but have not done anything for over an hour.
CPU and RAM do not indicate much activity.
Solution:
It feels iSeries AS/400 (IBM) has corrupted .net framework. Reinstalling .net framework fixed an issue. I hope it helps someone.
