We are seeing ESF427 FCB IMAGE XXX NOT FOUND message for CA SPOOL for few printers.
This is appearing after z/OS 2.4 Upgrade. The older SYS1.IMAGELIB has been copied the current SYS1.IMAGELIB, but still messages are appearing.
Release : 12.0
Component : CA Spool
The new SYS1.IMAGELIB created extents when the modules were copied.
Recycling the CA Spool started task corrected the issue.
