Here at SNS we have lately had problems with IOCs
crashing without leaving any trail for
Ø analyzing
what the problem was
For Linux IOC’s I would build debug
and turn on core file production. For vxWorks I understand that vxWorks 6.0 introduces
capabilities to debug crash files post mortem, but I currently don’t have
personal experience with that new feature.

Subject: Serial port access and
loging services for IOCs?
Here at SNS we have lately had problems with IOCs crashing
without leaving any trail for analyzing what the problem was. We have our
own home grown procServe and we are looking into the iocConsole/screen software
that SLAC is using. We are different from SLAC in that we use Digi port
servers with a driver on one of the linux servers that maps port server ports
into local /dev/ttyXXNNN devices. We just use 'cu' to open a serial
port. IocConsole does not support that but making it do so would not be
hard I don't think.
Looks like a modified iocConsole is our best option but
before we commit to it we thought we out to see what others are doing to
capture the last few lines of terminal activity from running and crashed hard
IOCs.
