The first time i get hartko@vwagwolkf320:~/dropwatch/src$ ./dropwatch Initalizing kallsyms db dropwatch> start Enabling monitoring... Kernel monitoring activated. Issue Ctrl-C to stop monitoring But Ctrl-C does not work. I only get 100% CPU load on the CPU executing dropwatch. After killing the process, i get the above originally described behaviour. >> >> And in my kernel log i get at the same time: >> [ 7070.568482] netlink: 60 bytes leftover after parsing attributes. And this comes every time, i invoke dropwatch. I'm running a debian system here on a Dell 830 Laptop with Core2Duo and the latest linux-2.6 git Regards, Oliver ps. Do i need to be root to run dropwatch?
