Undelivered messages in /usr/spool/mmdf/lock/home

If cron(C) queues a file with this error message in /usr/spool/mmdf/lock/home/q.local to be delivered to the sys user:

   To:sys
   

   cron: can't change directory to your home directory.
   Your commands will not be executed.

Other symptoms of this problem are these errors:

• Out of inodes on dev (1/40)

• Out of space on dev (1/40)

• no more processes

• no file

To resolve this problem:

1. Recreate the /usr/sys directory by logging in as root and entering these lines:
   
   mkdir /usr/sys
   chmod 755 /usr/sys
   chown sys /usr/sys
   chgrp sys /usr/sys

2. If your disk filled up due to the problem, recover disk space by entering:
   
   cd /usr/spool/mmdf/lock/home

   and removing the messages in the addr, msg, and q.local directories.

   Clean the log files by entering:

      > /usr/spool/mail/sys
      > /usr/spool/mail/adm
      > /usr/spool/mail/root
      > /usr/mmdf/log/msg.log
      > /usr/mmdf/log/chan.log
      > /usr/adm/messages
      > /etc/wtmp
   

3. Boot the system. Enter the root password to bring up the system in single user mode when you see this prompt:

      Type <ctrl>-d to proceed with normal startup,
      (or give root password for System Maintenance)
   

   At the prompt, enter:
   
   /etc/fsck -s /dev/root

   This file system check with an s option updates the free list of available inodes and blocks in the superblock.
