[j-nsp] Junos 10.0 stop responding when issuing a command

[meryem Z]

Hello Community,

I have a problem with an m7i router with junos 10.0 installed. When issuing somme commands like "show log messages", the router hangs and stop responding.
I checked cpu (~20%)and memory (~50%)load and it seems normal.
Have you ever met this kind of problem ? is it a bug in the OS? i have this problem with many routers , with junos 10.0 or 9.6.

Thanks for your help.
