Ø  Error (511,511) PV: 13SIM1::TIMEZONE devStringinEnvVar (init_record) Illegal INP parm field

 

I now understand this problem.  The iocStats file Db/iocAdminSoft.substitutions contains this line:

 

        { "$(IOC)" , TIMEZONE     , EPICS_TIMEZONE                  , epics  }

 

The problem is that as of 3.15.7 the EPICS_TIMEZONE environment variable has been replaced by EPICS_TZ.  Replacing  EPICS_TIMEZONE in this file with EPICS_TZ eliminates this error.

 

The question is how to modify this file so it will work on versions before and after 3.15.7.

Hi Jakub,

 

I have been seeing both of those messages on my areaDetector IOCs as well.

 

Ø  Error (511,511) PV: 13SIM1::TIMEZONE devStringinEnvVar (init_record) Illegal INP parm field

 

That message happens every time the IOC boots for me.  I have been assuming is a problem with devIocStats, and have been meaning to track it down.

 

Ø  callbackRequest: cbLow ring buffer full

 

That message only very occasionally happens for me at the end of iocInit.  I believe it happens when the number and rate of driver callbacks for PVs are too large, so that the queue in EPICS base overflows.  We could probably eliminate them by increasing the size of that queue.  But before doing that I want to know why they just started happening, and I did not see them before.

 

I am running base 7.0.3.1 and the master branch of asyn.  The question is whether it was a change in either of those that caused the messages to start happening.

 

Note that this error can actually be serious, because it means that some records will not have their correct values, because the callback events were missed.

 

Do you see those cbLow messages every time you boot?  What version of base,  asyn and ADCore are you using?
