Hi Zibi, Interesting. If the TCP/IP server is indeed running on the Raspberry, it should be enough with an init on the Tango DS. We have not experienced this before. Let us know if it happens again, Thanks a lot, Jens
Hi,
We are using commit: 95a32ee (merge pull request #6 from MaxIV-KitsControls/issue-4).
We have observed this issue twice already. The Tango device RaspberryPiIO gets into the FAULT state.
while the tcpserver on the raspberry pi is running:
Restarting of the RaspberryPiIO DS from Starter did not work. I had to restart the tcpserver-raspberry_pi on the raspberry pi and again restart the RaspberryPiIO DS.
This time it took like 35 days since we restarted it last time, but we don't know at which time it went into the FAULT state.
First of all, have you observed this kind of behavior?
In order to improve the post mortem analysis I uncommented the debug traces from
catch_connection_error
decorator and enabled the Tango logging. This way, at least, we should know at which moment it happens (there is polling enabled on some of the attributes). Do you know any other way on how to investigate this issue?Many thanks in advance!
