Description (partial)

Symptom:
-F2 line card will enter a booting loop state when reload event takes place
-Seems to be only reproducible if the amount of "vpc orphan-port suspend" command in the configuration goes beyond 200.

Following errors can be seen when system is coming up:

%$ VDC-1 %$ %VDC_MGR-2-VDC_CRITICAL: vdc_mgr has hit a critical error: Creation of default vdc failed!

%$ VDC-1 %$ %VMM-2-VMM_TIMEOUT: VDC1: Service SAP Mcecm SAP for slot 6 timed out in INSERT_SEQ sequence

%$ %VDC_MGR-2-VDC_CRITICAL: vdc_mgr has hit a critical error: Creation of default vdc failed!

Conditions:
-Reload event needs to take place
-Reproducible in 7.x and 8.x codes
-There needs to be about 200 lines in the configuration for "vpc orphan-port suspend"
