Fast stream-device IOC suddenly disconnects

[Abdalla Ahmad via Tech-talk <tech-talk@aps.anl.gov>]

Hi

 

We have a device streaming data at 200 Hz controlled with stream device, parses the streamed data and writes to corresponding PVs. The problem is that every day or two, the readings freeze. At first I had to restart the IOC but I noticed that the IOC does not show any error so I re-connect the asyn port through writing 0 to the CNCT field and it worked. The st.cmd file has the port configured:

 

drvAsynIPPortConfigure(“PORT”, “ip-address:port-number”, 0, 0, 0)

 

What could be the issue here? I am using EPICS base 7.0.9 and latest version of all modules.

 

Best Regards,
