After installing VAAI 1.2.3 plugin on ESX 6.0 server, log file /var/log/isi-nas-vib.log can grow unbounded, eventually filling up /var partition and can cause ESX server to become unresponsive. The log file will continue to be recreated after it is removed.

VAAI 1.2.3 plugin was built with debug enabled by default

WORKAROUND

Uninstall VAAI 1.2.3 plugin until a fix is provided.

OR

Setup a cron job on ESX 6.0 server to periodically remove the log file:

1. ssh into ESX server and login as root user

2. edit /etc/rc.local.d/local.sh, and add the following lines toward the end, before “exit 0”:

/bin/echo ‘*/15 * * * * /bin/rm /var/log/isi-nas-vib.log’ >>/var/spool/cron/crontabs/root

/bin/kill -HUP $(cat /var/run/crond.pid)

/usr/lib/vmware/busybox/bin/busybox crond

3. The reason for the above step is so if ESX server reboots, the workaround will persist after reboot. But at this point workaround has not been set on the ESX server yet.

4. Manually run the above 3 yellow-highlighted commands to implement the workaround on the current ESX server session.

5. Monitor /var/log/syslog.log and make sure you see every 15min an entry such as:

2017-10-03T15:15:01Z crond[35429]: crond: USER root pid 38236 cmd /bin/rm /var/log/isi-nas-vib.log
