Hi. For five days in a row now I've been having the same issue. 2 days ago I upgraded to a never snapshot in case it would fix my problem without luck.
This is @home on a DSL lines. OpenBSD gateway is connected to the modem with an axe(4), default setup, nothing fancy running... Every night I'm doing an rsnapshot backup off site of a small amount of data (couple of Gb). This setup has been running for about a year. Since 5 days, the connexion hangs during that backup, everytime. My logs are empty and the only way to get net access again is to: # pfctl -d ; sleep 2 ; pfctl -e pyr@ and I couldn't find anything obviously wrong. I'm not sure where I should start to debug this and would appreciate any hint. Thanks.
