Yesterday, I was running tcpdump, paging the output with less. All of a sudden, less started to dump core (SIGSEGV). I could not even start less by itself:
> less
without it getting a SIGSEGV, and in fact no user could run less without getting a SIGSEGV, but it did work perfectly a few minutes earlier. This morning, I tried to run less again, and now it was working! No core dumps!
How can this happen? Something overwriting the page/buffer cache? Unfortunately, I don't know how to reproduce it. I'm writing this because it was so strange that I felt I had to share it. There are no messages in the (dmesg) log.
/Tobias, a little bit worried
