Hello Robert,
It seems like Junos is internally sending the certain commands to JBCM which is not supported being recognized. That is the reason SRX is printing "unrecognized command". These are not harmful events and can be ignored.
I'm not sure about the Junos version which you are running but these messages are removed from Junos 19.4R1 onwards. If you think these logs are overwhelming, either you can upgrade the code or you can mask these messages via configuration using - set system syslog file messages match "!(.*DAEMON-3-LIBRESOLVER_DNS_SERVER_REPLY_ERROR_CODE*.*)"

Subject: Log file events JBCM
Getting repeated events of the following:
JBCM(0/0):jbcm_eth_get_info: unrecognized command (110) 2021-03-16 13:23:19.236
JBCM(0/0):jbcm_eth_get_info: unrecognized command (108) 2021-03-16 13:24:19.233
I searched and Googled but can't seem to pin down what the cause is.
Any help is appreciated.
