Detailed information about the server construction can be found in JGW-T2617453.
A ca-gateway process is now managed by systemd + journald, so it can be operated by
systemctl {start|stop|restart|...} ca-gateway.service
journalctl -u ca-gateway.service
Now following logs are recorded but it doesn't seem to be an issue on ca-gateway.

According to Ikeda-san's check, it comes from duplicated launching of pcas process by each application
and he will fix it on a future maintenance day.
Anyway, the ca-gateway server was upgraded properly from expired OS to modern one.
K-Log#37272
According to Ikeda-san's check, it comes from duplicated launching of pcas process by each application and he will fix it on a future maintenance day.
Two PCAS server instances were being launched for each device, so I removed the redundant server instance.
The affected devices are Picomotor, Stepper (VIS and CRY), and Traverser.
I verified that Picomotor and Stepper (VIS) are working properly. The code for Stepper (CRY) and Traverser has also been updated.
Their operation will be verified the next time they are used.
[Before]
class PcasServer(pcaspy.SimpleServer):
def __init__(self, prefix, driverIP):
super(PcasServer, self).__init__() # Creates the first instance
self.server = pcaspy.SimpleServer() # Creates the second instance
def __init__(self, prefix, driverIP):
super(PcasServer, self).__init__() # Creates the first instance
self.server = pcaspy.SimpleServer() # Creates the second instance
[After]
class PcasServer:
def __init__(self, prefix, driverIP):
self.server = pcaspy.SimpleServer()
def __init__(self, prefix, driverIP):
self.server = pcaspy.SimpleServer()
