DB queue pending jobs

Hi,

until this morning everyhitng was working fine but we don't know what could be changed, that now every AD group assignment (direct or indirect through dynamic role) is not being provisioned to AD.

We have seen on Job Queue Info - DBQueue that we have 6 pending jobs to be processed.

To process:6

Processing: 0

Sort Order: 839990

Is Reset:Yes

Operation: Active Directory user account memberships in Active Directory groups (Active Directory)

Any idea what could be happened?

Thanks!
