## Symptoms

- * ISO Installation via LOM and KVM Console stops after several hours with the following error message: `video socket error: abnormal termination`
* The installation phase is longer than one hour.
* The installation is successful only if the user clicks on the LOM web session tabs to keep the connection up.

## Cause

The issue is related to the Java video session using a LOM version lower than v2.43:

When the web session encounters a timeout, the user is redirected to the login page, at which point the Java video session (Terminal-Session and Media-Sharing) runs into a "video-socket error," and the image installation stops because of the missing image location. The installation of the base image lasts about 2 hours and can be resolved when the user clicks on the LOM Web console tabs of the web session to keep the connection running.
