This doesn't happen anymore with the unstable version (2:4.7.0-pre1-3). Could you try testing that and see if it indeed works for you (maybe by building it for lenny?) While this is indeed unpleasant, the fact that mc eats a lot of memory should not kill the whole system, and is more likely a wrong system configuration, I think. regards, iustin -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
