Are home directories using NFS? Is nsswitch using LDAP for account (passwd)
lookups?

With NFS, (and especially automounters), you could be running into
STALE NFS file handles...
With LDAP you could be running into issues doing the passwd lookups.

This makes it as far as deliver_mailbox(), and should (given the home_mailbox
setting) after:
if ((mbox_pwd = mypwnam(state.msg_attr.user)) == 0)
return (NO);
proceed to deliver_maildir()
...
} else if (*var_home_mailbox && LAST_CHAR(var_home_mailbox) == '/') {
path = concatenate(usr_attr.home, "/", var_home_mailbox, (char *) 0);
status = deliver_maildir(state, usr_attr, path);
myfree(path);
}
But the code aborts before getting that far, without logging a reason, so
this abort() is in code called from mypwnam(), the only way to do that
is a failure in getpwnam(), which is a non-Postfix issue...

Find out why getpwnam() aborts the local delivery agent...
