Hello
i have a running 877 without any issues since 2 years, but recently it start to reload accidentally without any reason and every time i lose part of the configuration (DHCP configuration) so i need to reconfigure it again.
i updated the ios from 124-15.T4 to 124-24.T8, now the configuration is stable even after reload, but the reload problem still exist. is there any solution?

2. any CPU high load ?

- I would advice to use standard upgrade and installation procedures from Cisco , especially when dealing with issues such as you are experiencing. Use show version as a sanity check as to query the current version running. Besides other reply also use a syslog-server as a log collector and also use an snmp-trap receiver for all traps. The intend is also to be able to watch for problems during normal behavior. Indeed you can then also look for last-gasp information when a device reboots.
