When downloading to one of the eight safety controllers the MMS fails to all other seven, and also the MMS read fails on the controller we are downloading to. From the controller log it would appear the fail occurs when the download stops/restarts the application
PTimeout 10s, PStartUpTimeout 30s on all controllers
Controller has been switched to other (lower) CPU and problem persists
This only happens with one of eight controllers, PM865 FW 5.0.2410.28
20% application, 75% Total load
Has anyone encountered this problem, and if so found a solution?
Note the recommendation to keep maximum total load in a HI controller below 70%. There is also issues with failed MMS client connections consuming additional total load (3-5%), however this relates to newer fw (5.1.1-1 to 5.1.1-3 and 6.0.0-0). (Check in Remote System dialog for transactions like 0 trans/sec.)
(And yes, have seen this under similar circumstances with more recent versions of fw.)
