the nodes have 32G ram, there are no other processes running. Thanks for the info about the g1gc. I used bootstrap resume to finish the bootstrap, then added another two nodes. This worked, but I saw in munin a constantly rising memory consumption during streaming, while on the other nodes there was a constantly amount of memory used. Nothing was killed this time, since the streaming took much less time to complete. I think I'll switch to cms on the problem node and compare the memory usage and compare the nodetool info output.
