Hi Marco,

I see this failure when the soft ioc failed to start.  There are other system-related reasons. 

Currently, the LCLS group at SLAC is changing to no longer start soft IOCs using the SLAC version of iocConsole and instead will use something called procServ - Ernest can give details.  Apparently, the soft IOC can freeze while somebody is paging up and down inside of screen - I've not reproduced it and debugged it though.   I also see that Ralph Lange uses something called conServer which looks interesting:

Sorry I cannot be more help,

Stephanie Allison
