The issue occurs because the DSVA ran out of disk space due to very large /var/logmessages.1 and /var/log/syslog.1 files.

To verify:

  1. Open the DSVA console and press ALT + F2.
  2. Log in using "dsva" as the username and password.
  3. Check the file systems using the following command: dsva@(none):~$ df -k

    You will see results similar to the following:

    log files consuming DSVA disk space

  4. Check the log files of /var/log/messages and /var/log/syslog using the following commands:

    dsva@(none):~$ cd /var/log
    dsva@(none):~$ ls -alh

    The following results will appear:

    huge messages.1 and syslog.1

To resolve the issue, delete the log files that are consuming too much disk space.

  1. Use the following commands to delete messages.1 and syslog.1 from the DSVA:

    dsva@(none):/var/log# rm syslog.1
    dsva@(none):/var/log# rm messages.1

  2. Reboot the DSVA.
  3. Reconfigure the IP address and hostname of the DSVA.
  4. Reactivate the DSVA via the DSM.

If the issue reoccurs on a regular basis, contact Trend Micro Technical Support and request for a copy of DSVA Hot Fix Build 1814.
