Hi, Following the Riak fast track I'm stuck at the map reduce phase.
I've tried the following with devrel 4 nodes on the same box and 4 distinct virtual boxes with riak rel, same thing appends. Cluster is working fine, can put and get data, everything explained in the fast track work as expected until the map reduce test. Every time I do a map reduce, 2 or 3 nodes crash, the rest is unresponding. Not always the sames nodes, but always result in an unusable cluster. No nodes are responding, either crashed or not responding. Tried the simple map reduce and the others examples. Also tried to switch to legacy map reduce, same thing. (using "application:set_env(riak_kv, mapred_system, legacy)"). System is Gentoo on a 3.0.6 kernel. 512 Mb of ram for each box (60 Mb used after boot, including riak). Erlang 14B03 Riak 1.0.1 (From source, from the download page) Only thing changed are the node's name and IP's. Time line: +00s Cluster running (since hours), all nodes OK, responding to requests. +10s Starting map reduce query: "curl -X POST http://192.168.0.35:8098/mapred -H "Content-Type: application/json" -d @simple-map.json" (simple-map.json is taken from the fast track page and the goog data is inside the cluster, readable by a direct get) +11s All nodes start hogging cpu (>80%) +12s riak 1 and 2 crashes, see logs attached. riak 3 is running but not responding (cant input console) and using 100% cpu. riak 4 segfault. (see logs too) +99s Still in the same state, riak 3 still at 100% CPU, other obviously still crashed :) Attached logs for each nodes, and log for the query. Am-I missing something? Thanks in advance Regards Alexandre Ravey
