This sounds similar to, but not exactly the same as a problem we had on one
of our nodes.

After a period of time, we were unable to open the CAD on some of our WP's.
In our case it turned out that one of our cleanup scripts was removing
"stale" files in /tmp/ Files of names similar to _amAMA403 are created at
boot time, and are the license files for the alarm handling software.
removing these files will prevent the CAD from starting.

However, in our case rebooting the WP's caused these to be created in
normal system startup, and all was well, until we shot ourselves in the
foot with the cleanup scripts.

Check on the WP's and make certain you have these files.

But, I think you must have a different problem.
