got htis error and wondered if any one else experienced this and what the solution was.
object-group service AD_Client_Ports tcp-udp
port-object eq 135
ERROR: Unable to add, access-list config limit reached
Adding obj to object-group (AD_Client_Ports) failed; cause access-list error
However I was able to add an entry to an acl using 'eq 135' instead of an object-group.
