Packages Stuck at "Waiting to Install"

[doingIT]

I am having trouble with newly imaged machines and packages being stuck at "Waiting to Install". When I look at the execmgr.log I get the following:

 

Package AMR00005, program Silent is ready but can not be started because package , program is currently running.

Raising event:
[sMS_CodePage(437), SMS_LocaleID(1033)]
instance of SoftDistProgramWaitingForAnotherProgram
{
AdvertisementId = "AMR2006F";
BlockingPackageID = "";
BlockingProgramName = "";
ClientID = "GUID:918217e5-8cb3-4280-ac5b-754be62957ec";
DateTime = "20150717175355.461000+000";
MachineName = "testvm01";
PackageName = "AMR00005";
ProcessID = 852;
ProgramName = "Silent";
SiteCode = "AMR";
ThreadID = 548;
};

The problem I am faced with is that the blocking package seems to be a ghost package as the name and package ID is left blank. Has anybody ever seen anything like it before? My guess is that there is a program in my OSD task sequence that gets stuck, but the TS completes fine and without error. Can someone please chime in? Thanks in advance!
