Experimental Physics and Industrial Control System
Everyone...
We are currently running a Soft IOC on a Linux based PC, and are using
it to communicate to a Modicon PLC, using the Mark River's Modbus
software. This IOC currently has ~4000 PV's on it.
A few months ago, we upgraded the epics software on this IOC to include
the Auto Save/Restore. We are saving 258 PV's every 10 seconds, and an
additional 258 PV's every 10 minutes.
This has worked fine, but we have discovered that, over a few days, the
load steps from less than 1, on up to 5, with the CPU at %100. We
never noticed this behavior prior to installing Auto Save/Restore, and
don't have this issue with any of our other IOC's.
Any thoughts/ideas on what may be causing this? Thanks...
