At the EPICS meeting last week Till asked: 1) Could we declare a maximum priority for any component of base? 2) Why does iocsh run at epicsThreadPriorityMax? Brief discussion. 1) sounds like a good request. How about epicsThreadPriorityBaseMax = 912) I will assume that this was done to be like vxWorks, which runs the vxWorks shell at highest priority. If iocsh runs at epicsThreadPriorityBaseMax it seems like it should be OK. If a very high prority application thread uses all the CPU time iocsh can't get control but this is the applications problem.
Comments anyone? Marty
