Ok Thomas. I got a stall on my desktop. It happens when I try to use sudo and it just stay stalled (I think trying to access /dev/log or something like that). I got the trace here: http://www.abusar.org/ftrace/trace.txt.bz2 after the stall. Could you please check if there's something wrong? I'd prefer if the stall happened in the server, but it still didn't happen. Anyway, it's the same problem. Ps: this time I couldn't solve it with nmap (sometimes nmap solves, sometimes it doesn't). Ps2: in this stall, the tracing wasn't disabled automatically by your patch, because it happened in a different situation (when I tried to use sudo). But I know it's the same problem, because the "solution" I use is always the same (nmap) and until it's not stalled anymore, I can't connect to any port on my machine. Ps3: if this trace is useless, wait until I get something on the server. --
