I have various mikrotik routers and switches, but only one CRS328 has intermittent timeouts when trying to ssh or webfig in. Serial console always works and is snappy. Since do not have problems with other devices, and a 2nd CRS328 (newer and not loaded) does not have this problem, and they are all configured closely the same, I'm not exactly sure what to look at or for.
CRS328-24P-4S+, about 2 years old, 6.46.6, IIRC started to have problems about 6 months back, thinking software update, but not 100% sure. Almost all ports in use, however traffic is light (sub 1Gbps mostly). As I write this I cannot ssh/webfig in. From the serial console the cpu load is 3%. Free memory: 494228KiB.
Looking for suggestions. Thanks.
