Hi Shiju,
Did you raise an incident with SAP? If not, you should probably do it..
One option you have is to change the "queued" to "ready to run" status directly in IDM database using below query.
update mxp_provision set state=2,prevstate=State where state=37
***This is not recommended until you know what you are doing***
if you want to know the consequence just try for one user using below query,
update mxp_provision set state=2,prevstate=State where state=37 and mskey = <mskey which is in queued status>
Kind regards,
Jai
