The plock() function appears to fail with ENOMEM (Not Enough Space). When
|
||||
it fails, it consumes a lot of memory. This appears to be an AIX bug. I
|
||||
think plock returns an error code, but it partially succeeds to lock some
|
||||
pages, thus increasing memory consumption. When partial failures occur, it
|
||||
is possible that AIX fails to unlock those pages it did lock. Solution:
|
||||
turn off usage of plock on AIX. Put plock=no in your amd.conf file (which
|
||||
is the default if you do nothing).

* amd/amfs_auto.c (amfs_auto_bgmount): patch from Nick Williams
|
||||
<njw@ms.com>. SYMPTOMS: 'occasionally' sublinks do not point to
|
||||
the correct location, but to the top level of the mountpoint and
|
||||
an (error-hook) is seen being mounted in the log file. This causes
|
||||
things to Go Wrong(TM).
|
||||
CAUSE: When evaluating two locations which are requested
|
||||
'practically simultaneously', and the two locations resolve to the
|
||||
same NFS mountpoint (but different sublinks), the later request
|
||||
will be "deferred" and retried after wakeup when the first mount
|
||||
succeeds. To do this, it rewinds the options location string to
|
||||
re-evaluate the location when the mount is retried. However, it
|
||||
shouldn't rewind the options for two reasons: (a) the semantics of
|
||||
the map language say you shouldn't and (b) the NFS mount reference
|
||||
is not reset at the same time, meaning that on the retry it will
|
||||
have an options structure out-of-sync with the mount
|
||||
structure. The "shortcut" code when retrying the mount sees the
|
||||
mount structure is already filled in and does not fully evaluate
|
||||
the options structure.... so if the first location is not the one
|
||||
which ties in with the mountpoint (see ordering in the
|
||||
recreate-by), you're now well messed up.

*** Notes specific to am-utils version 6.0.2:
|
||||
|
||||
- safe map reloads: when a map needs to be reloaded, it is reloaded into a
|
||||
temporary copy first. Only if the reload was completely successful, Amd
|
||||
discards the old map and uses the new one. Otherwise Amd continues to use
|
||||
the old maps. This should help a lot with transient NIS problems.
|
||||
|
||||
- amq -f now also forces a (safe) map reload, but only if the timestamp on
|
||||
the maps was updated.
|
||||
|
||||
- two new selector variables: ${vendor} and ${full_os}, which are the same
|
||||
as the output seen in "amd -v".
|
||||
|
||||
- documentation fixes and updates
|
||||
|
||||
- updated or minor new ports:
|
||||
i386-unknown-freebsdelf3.3
|
||||
|
||||
- support 'ignore' flags (automntfs) in bsdi-4.1
|
||||
|
||||
- bugs fixed:
|
||||
expn.pl uses correct sockaddr_in() not, pack()
|
||||
make sure configure --enable-*args take an argument
|
||||
don't busy-loop trying to rebind to ldap servers

use vsnprintf, not vsprintf (security)
