Hi John,

We have not seen any problems of this nature here. We are
controlling all of our klystrons through IOCs based on the
vxWorks PC486 BSP.

Please follow the advice of the message below and e-mail to me
the stack trace output from "tt (0xnnnnn)" after the "CA online" 
task is suspended. This will greatly reduce the time required to
isolate the cause of your problem.

Also please send the output from the vxWorks "version" command
and indicate what drivers, devices, and or non standard records
are loaded and initialized in this system.

thanks for bringing this to our attention

Jeff
