Unlikely to be related. The error messages above are because the page is misusing <title> tags, but that won't cause a segfault. Were the error messages really truncated as above, or did this only happen when copying and pasting into your mail program? > After the SIGSEGV the machine was in an unstable state, with impossibility > to log in even as root, and most commands on the shell giving SIGSEGV > (like ls, find etc), but sometimes working.

I highly recommend a kernel upgrade. There's no point trying to track down any other mysterious problems if you suspect the kernel. If upgrading to a stable version of the kernel doesn't clear up all the problems, then you can start looking elsewhere. Checking the memory might not be a bad idea. > I went looking on the web and I found this: > > http://search.uni-heidelberg.de/htdig/local/FAQ.html question 5.14 Yes, the latest FAQ is also available at http://www.htdig.org/FAQ.html You've already followed the relevant advice from there when you did the backtrace in gdb. It still doesn't help pinpoint the problem, but it sounds like the problem goes beyond just htdig. > I also think that someone has been playing with my security lately.

I > will update asap. It's always a good idea to take security precautions. However, if your kernel is unstable, there can be all sorts of wierdness happening on your system, some of which might seem like hacker activity but isn't necessarily that. The best precaution is to get your system running reliably. > your opinions would be welcome. Btw I fuond that juggernutz person in > google. He says that he is educated.

I don't see the connection here to the htdig problems we were discussing. -- Gilles R.
