Looks like pin to track clearance causes some of your problems, you may enable
auto enforce drc and try to route track manually between pins and see if it fit at
all, if not then change clearance lets say to 8mil, and try again. Usually
its doable to place one track between two adjacent 0.1" spaced pins, i was told
that one put two tracks between them, but i haven't seen that myself.
