Due to an installation mistake (somehow rpm messed up) I ended up with an passwd
|
|
file which didn't have a rpc entry. This meant that during startup the
|
|
getpwnam() call to determine the details for user rpc caused the normal process
|
|
for passwd lookups to be followed. For me this meant after looking at
|
|
/etc/passwd the lookup tried to use NIS. This of course deadlocked since as
|
|
part of the NIS lookup rpcbind has to be contacted.
|
|
|
|
The workaround is quite simple: use __nss_configure_lookup() to restrict
|
|
the lookup.
