Hello. The proble now seems to be not directly sleep-related but rather network-related one. I've noticed that my rtorrent process had gone away and tried to start it but got the error alike that. Tried to strace it and seen that it sends SIGABRT after receiving many "no route to host" errors. After that, I've found that my wifi just gone away and there are indeed no routes.
So the problem now seems like rtorrent suddenly (for it) realizes that there are no reachable hosts [of some kind] and aborts. My ~/.rtorrent.rc is as follows: session = /home/ap/.rtorrent dht = auto dht_port = 6881 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
