Hi List,
We are using RH 8 2.4.20-28.8 kernel for our machines. The following messages suddenly showed on our consoles:

We found out that pressing Ctrl-Scroll lock on the keyboard dumps the memory information to dmesg and the syslogs. We thought its only the magic SysRq key that could have caused this as the effect is like pressing Alt-SysReq M. So we checked the status of the sysrq and found that it is disabled:
# cat /proc/sys/kernel/sysrq 0
Can anyone give us a hint what else could cause the memory dumps ? Is there a linux command that can show the same output?
Would appreciate any clue :-)
cheers,
