v6.12 - interface print hang?

Anyone has an experience where you issue /interface print and it hang on a remote telnet session?

For example the following:

[admin@DDD] /ip> /interface print
Flags: D - dynamic, X - disabled, R - running, S - slave

NAME TYPE MTU L2MTU MAX-L2MTU MAC-ADDRESS

0 R ether1-WAN ether 1508 1598 4074 D4:CA:6D:F7:D9:0A
1 S ether2-LAN ether 1500 1598 4074 D4:CA:6D:F7:D9:0B
2 ether3 ether 1500 1598 4074 D4:CA:6D:F7:D9:0C
3 ether4 ether 1500 1598 4074 D4:CA:6D:F7:D9:0D
4 ether5 ether 1500 1598 4074 D4:CA:6D:F7:D9:0E
5 ether6

— END —

Could it due to MTU size?
