Issue/Introduction

Boot messages from cbsinit: "warm" versus "cold" restartDuring CPM boot, there may be log messages similar to these:

Sep 29 03:45:47 cp2 cbsinitd[3585]: [I] cbsinitd 7.2.1 [Oct 30 2007 16:09:52] (bldmgr) starting
Sep 29 03:45:47 cp2 cbsinitd[3585]: [I] Copyright (c) 2000-2010 by Crossbeam Systems, Inc. All rights reserved.
Sep 29 03:45:47 cp2 cbsinitd[3585]: [I] warm restart
Sep 29 03:45:47 cp2 cbsinitd[3585]: [I] Polling rate is 10 second(s)
.
.
.
 

Although maybe some distance in log terms (and hence not obvious), there will also likely be messages like these also:

Sep 29 03:44:49 cp2 cbsinitd[1517]: [I] cbsinitd 7.2.1 [Oct 30 2007 16:09:52] (bldmgr) starting
Sep 29 03:44:49 cp2 cbsinitd[1517]: [I] Copyright (c) 2000-2010 by Crossbeam Systems, Inc. All rights reserved.
Sep 29 03:44:49 cp2 cbsinitd[1517]: [I] cold restart
Sep 29 03:44:49 cp2 cbsinitd[1517]: [I] Polling rate is 10 second(s)
.
.
.

Resolution

These are potentially confusing in their references to cold versus warm restarts. This does not in any way relate to the nature of or method of rebooting the CPM (i.e. Linux reboot versus CB reload versus pull the card, etc.)

The references to the type of restart relate entirely to cbsinitd itself. Under certain circumstances, which do not matter here, during an otherwise normal CPM boot cbsinitd will start up (the first, "cold" start of cbsinitd) and then later will stop and be restarted (the second, "warm" start)

During a cbsinitd-warm-restart it handles script execution in a slightly different manner from how it does so during a cold-restart.

In effect, the messages can be safely ignored.
