Subject: IOC Errors when StripTool is Running

Chris, can you give us help with apparent problems we are having with
StripTool?

>From a message I got from a colleague of mine (Delphy Nypaver):

"I ran a test this morning and it appears that it is the StripTool that is 
causing the memory problem. Every time I run it I get those errors on the 
ioc. My theory is that the reason rebooting the Sun caused the problem to 
go away is because it killed the StripTool program when it rebooted."

>From a previous message Delphy sent documenting the error messages she gets:

"Attached are the intermittent memory errors we are getting on the ioc. I 
would think some of your contacts in the EPICS community would be able to 
tell us what these mean, if not what's causing them."

Have we possibly overlooked something in how we use StripTool?

Again, from one of Delphy's messages:

"There didn't seem to be a relation with the alarm handler, but I'll keep 
checking. Error messages also print on the Sun about invalid channels that 
aren't invalid unless the StripTool is running."

Any help here with understanding better how channel access works will also
be appreciated.

Regards,
