I've seen this on stacked 3750s when doing "anything" related to configurations, it would hang up hard enough to timeout EIGRP hellos from neighbors (and vice versa) causing general havoc everywhere.
The workaround was to include "parser config cache interface". During the "hangs" if you could get another CLI session up the show proc cpu sort list would show the stack configuration replication process eating up the resources. That wouldn't really apply to 6500/7600 but just in case, thought I'd throw that one in there (it's a harmless configuration addition as far as I'm aware).
