Not on the list, but given the sender, I think he found me elsewhere,
and we debugged it.

Yes, it should be fixed in slapi-nis 0.50.  That version reconnects to
rpcbind if rpcbind has dropped the connection from the plugin since the
plugin last connected to rpcbind (the plugin connects first before the
server drops privileges, then after the server drops privileges, it
computes the contents of map entries, and it only sends the registration
request to rpcbind once it's ready to answer client queries).

It turns out some RPC libraries (which rpcbind links with) will
disconnect clients which they consider to be "idle" after some period,
and that was biting us because computing map contents was taking more
than that length of time, in part because the search filter that was
used to select entries for use in populating NIS maps was referring to
attributes that weren't indexed.
