Issue/Introduction

1. The SSP appliance running on ISG OS 2.5.1.1 encounters an unexpected restart.

2. In the SSP diagnostic logs (/var/log/messages), the following exception is observed:

ERROR Exception: ConfException - unexpected end of file
com.tailf.conf.ConfException: unexpected end of file
    at com.tailf.conf.ConfInternal.readFill(ConfInternal.java:505)
    at com.tailf.conf.ConfInternal.readSize(ConfInternal.java:435)

    at com.bluecoat.clp.cli.ConfdSubscriptionManager$ConfdSubscriptionThread.run(ConfdSubscriptionManager.java:215)
Caused by: java.io.EOFException

3. The following errors are seen leading up to the reboot in /var/log/messages

password_protection_service.py[15741]: _confd.error.EOF: ConfD closed connection
systemd[1]: coe_webproxy_subscriber.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: coe_webproxy_subscriber.service: Failed with result 'exit-code'.
System rebooting due to error in upgrade/downgrade. Rebooting into previous system image.

4. We also see the following error message in clp_services.log:

Cause

This was caused by a third party component (confD) (an internal service) which failed and starts closing connections, causing the unexpected reboot

Resolution

The bug is addressed in 2.5.2.1 and above
