Symptoms

If a core file is found on a slave blade in a chassis, that is too large for qkview to include, this can cause the qkview file for the blade to be corrupted.

Impact

iHealth will not parse the qkview.

Conditions

qkview is run when core files greater than 2.4 GB exist in /var/core.

Workaround

Copy the core files on the slave blade from /etc/core to a back up location and delete the original files before creating the qkview.

Fix Information

qkview files run when core files greater than 2.4 GB exist in /var/core now complete as expected.
