[c-nsp] Cisco 7606 SUP32 running-config disappear

[Igor Kremez]

Hello,

We got the Cisco 7606 SUP32 IOS 12.2(18)SXF5.

Cisco Internetwork Operating System Software 
IOS (tm) s3223_rp Software (s3223_rp-IPSERVICES_WAN-M), Version 12.2(18)SXF5, RELEASE SOFTWARE (fc3)

Yesterday i mentioned strange problem, running-config disappear from the system: volume.
All my scripts where failed to update cisco config thru the tftp and SNMP but show running-config
and configure terminal from the tty where working fine. Write memory was working fine. 
Also i coudn't get running-config by SNMP.

Here is few outputs from the cisco and my scripts:

router#copy tftp://10.10.11.11/new_part.cfg system:running-config
Destination filename [running-config]?
Accessing tftp://10.10.11.11/new_part.cfg...

We reboot our router and everything back to normal.

Is it known problem with 6500/7600 series or we were just "lucky"
and the problem will never be back again?

Is there is any solution how to fix the problem without to reboot the router ?

Thank you in advance.
 
P.S. Sorry for my bad English.
