CAUSE
runMSList size6 means there are 6 managed servers in Run environment, patchMSList size5 means there are 5 managed servers in Patch environment, which caused error :
ERROR: Number of servers are not in sync between Run and Patch Context.

Run environment has one more managed server "oacore_server2" than Patch environment.
SOLUTION
Solution A: Remove/delete the managed server "oacore_server2" from the RUN environment filesystem
1.  Managed server oacore_server2 should be shutdown before it can be deleted(in this case, i shut down apache service with adapcctl.sh)
2.  Execute the below command on the Application tier node where the managed server resides:
# perl $AD_TOP/patch/115/bin/adProvisionEBS.pl ebs-delete-managedserver -contextfile=$RUN_BASE/inst/apps/UPG_apcappsx21/appl/admin/UPG_apcappsx21.xml -managedsrvname=oacore_server2 -servicetype=oacore -logfile=/tmp/remove_manage_server.log
NOTE: check the run filesystem context file for confirmation of no "oacore_server2" information
3. On the node containing the Oracle HTTP Server, run autoconfig:
# sh $INST_TOP/admin/scripts/adautocfg.sh
NOTE: The database server and database listener must remain available during the AutoConfig run, but all other database tier services should be shut down
4.  Execute the following script to remove details of the deleted managed server from the Oracle HTTP Server configuration files:
# perl $FND_TOP/patch/115/bin/txkSetAppsConf.pl -ctxfile=$RUN_BASE/inst/apps/UPG_apcappsx21/appl/admin/UPG_apcappsx21.xml -outfile=/tmp/delete_http_config.log
5.  On the node that contains the Oracle HTTP Server, bounce the Oracle HTTP Server:
$ sh $ADMIN_SCRIPTS_HOME/adapcctl.sh stop
$ sh $ADMIN_SCRIPTS_HOME/adapcctl.sh start
6.  Re-issue fs_clone phase
