[foxboro] Cyan Displays

 
We have faced similar problems, and in certain cases rebooting one of 

The FT pairs could resolve the problem . One of the probable reasons 

Could be the CP going out of resources (IPC channels not available) . 

You May investigate further using rsipc utilities .

Subject: [foxboro] Cyan Displays 

  

We had a rather unusual event earlier this week and I was hoping that 

someone might have seen something similar and can offer some 

explanation.  I was called by our field supervisor who told me that the 

workstations on all 4 of our nodes (which are connected via a carrier 

LAN) were getting cyan connections when displays were called.  I called 

up a stations display from a CP to an AW both on another node and it 

also displayed cyan connections.  After checking the system I found a CP 

that was failed in system management but was still "green" at the 

modules.  When this CP was rebooted all of the problems stopped and 

everything has run fine since.  The thing that is particularly curious 

is how a failed CP could cause errors across several nodes. 

Any information about a similar problem or any ideas on how this could 

happen would be greatly appreciated.
