Hello,
We are running several CA gateways for providing access to PVs for clients including OPIs.
I observed the warning message “Virtual circuit unresponsive” on log files of the CA gateways.
For instance,
Aug 28 15:29:19 Warning: Virtual circuit unresponsive 172.17.101.21:5064
Aug 28 15:53:40 Warning: Virtual circuit unresponsive 172.17.101.80:5064
…
In addition, when the message is logged on a log file, connections to PVs of the IOC server related with the message (ex. 172.17.101.21) are disconnected.
At the time, connection to the same PVs which directly connects to the IOC server instead of CA gateway is still continued and client (camonitor) can receive changes from the IOC without disturbance.
For the information, we are running two versions of CA gateways, v2.0.4.0 and v2.1.0.
Could anyone please share any guidance or comments in the case?
Thanks in advance for your guidance or any comments.
Regards,
Sangwon
