I was having this issue with RouterOS V4. V4 has been very unstable for us. A duplicate Supermicro router is running V3.30 without issue. I have reloaded the machine running V4 to V5Beta4 with good results so far.
So I’ve done some more experimenting with the x86 system.
I removed all IP addresses and disabled all firewall rules.
I created a 192.168.0.0/30 subnet with a spare mikrotik rb450 I have at home.
When I ping the x86 system I’m getting 54% packet loss!! Ping times are ranging between 0-7ms also. Should be all under 1ms as it’s only one 3 foot cat5 cable linking them.
System resources shows only 1% CPU utlilization and about 987 out of 1GB of ram free…
Anything I should do to keep narrowing down?
I also noticed this in the logs: login failure for user &[2~&[B&[B via local
