Hello to all,
I was on vacation for a few days. The sync (about 700 GB) was completed before I startet the trip, so btsync on the rPi was i a idle mode for more than 6 days.
What coul I say. The process did not crash meanwhile. I uploaded now some pictures to the sync folder of my PC (about 20 GB) and it synced well.
Maybe its only a problem with havy load over a long time, maybe a problem with i/o on HD? I have heatsinks on the rPi, but if it is a thermal problem, the whole rPi should be instable.
