Issue

A memory leak has been identified in the xpt_pool_ccb_alloc() function within the CAM subsystem, causing the BSD kernel to run out of memory (OOM) and triggering a system reboot via the nodewatchdog process. The issue appears to be related to improper cleanup of memory allocated for CAM CCBs during LUN deregistration events.
