FileWrite stopped working #18

I am having a problem with ADEiger.

I have enabled the FileWriter, and FWState_RBV is "ready".

DataSource is Stream, and I am getting the images over the Stream interface with no problem.

However, there are 2 problems:

1) There are no files appearing in the data directory on the Dectris server: image

2) If I change the DataSource to FileWriter there are no callbacks occurring in ADEiger. This is expected if there are no files appearing on the server. However, there are also no error messages in ADEiger, and no indication that I can see that something is seriously wrong. This seems bad since the user may think the files are being written OK.

I tried Initializing the server and restarting the IOC. That did not fix the problem. My next attempt will be to reboot the server and see if that fixes it.

Has anyone seen this type of problem before?

I vaguely remember having issues with the FileWriter. Sometimes it would stop working and require a restart of the SIMPLON API. It happened more often with older firmwares, I don't remember it happening at all in a few months before I left BNL. I'd advise to get the newest firmware version available from support@dectris.com (since they tailor the ISO they provide to each individual Eiger unit).

Also, try to keep AutoRemove set to Yes as much as you can. I think the detector gets confused if its disk starts to fill up.
