Solaris 2.6 NDBM problem

[Michael Smith <michael@csuite.ns.ca>]

Hi,

We recently installed ZMailer 2.99.52-patch1 on a Solaris 2.6 machine (gcc
2.8.1).

Every time the router tries to check the modification time or ownership of
an NDBM file (i.e. every lookup), it complains:

[2864] modp_ndbm: cannot fstat("/var/csuite/var/mail/db/fqdnaliases")!
[2864] modp_ndbm: cannot fstat("/var/csuite/var/mail/db/fqdnaliases")!
[2864] modp_ndbm: cannot fstat("/var/csuite/var/mail/db/localnames")!
[2864] modp_ndbm: cannot fstat("/var/csuite/var/mail/db/localnames")!
[2864] modp_ndbm: cannot fstat("/var/csuite/var/mail/db/aliases")!
[2864] owner_ndbm: cannot fstat("/var/csuite/var/mail/db/aliases")!
[2864] modp_ndbm: cannot fstat("/var/csuite/var/mail/db/localnames")!

The lookup (if any) still succeeds.

I stuck some code in router/libdb/ndbm.c:modp_ndbm() to check on the
values of dbm_dirfno() (used in the fstat() call) and dbm_pagfno():

z# router michael
<michael.interactive@phoenix.chebucto.ns.ca>: address: michael
modp_ndbm: dirfno 1155264, pagfno 0
modp_ndbm: cannot fstat("/var/csuite/var/mail/db/aliases")!
modp_ndbm: dirfno 1089392, pagfno 0
modp_ndbm: cannot fstat("/var/csuite/var/mail/db/fqdnaliases")!
modp_ndbm: dirfno 1089392, pagfno 0

modp_ndbm: cannot fstat("/var/csuite/var/mail/db/routes")!
(((smtp csuite.ns.ca michael@csuite.ns.ca g3)))

Those don't look like real file descriptors, especially since lsof
reports:

COMMAND   PID USER   FD   TYPE     DEVICE SIZE/OFF  INODE NAME
router  12314 root    4r  VREG     32,139    30587 620204
/var/csuite/var/mail/db/aliases.dir

router  12314 root    6rR VREG     32,139    24832 620205

router  12314 root    7rR VREG     32,139    24662 620203
/var/csuite/var/mail/db/localnames.pag

router  12314 root    8rR VREG     32,139    24576 620202
/var/csuite/var/mail/db/routes.pag

I realize this isn't a ZMailer problem, but has anyone seen this
before? Should ZMailer on Solaris default to btree instead of ndbm?

Thanks
