Hello I have two interfaces connected from a router J2350 (Junos 12.1X46-D35) to a switch EX2200(Junos 11.4R5.5) running rather ancient software
I had noticed im losing connection on one of the interfaces from J2350 to EX2200 with the interfacing going to up-down state on both devices while the other interface connecting the two devices does not flap. After investigation I have noted a ridiculous amount of log messages like below
chassism: Return code 1 not EOK: platform_an_periodic (1606)
chassism: Return code 1 not EOK: an_periodic (479)
This two messages happen every second essentially filling up all the 10 log files on the switch within a few hours.
After 20 minutes the link between the two devices came up, stayed up for an hour and went down again, then went down again for some time then came back up. It is still up for now it has been more than 5 hours but the log messages never stopped.
