Compactor crash and db file corruption

[ns_server:warn] [2012-06-07 12:23:23] [n_0@127.0.0.1:<0.3674.0>:compaction_daemon:do_chain_compactors:453] Compactor for vbucket `default/0` (pid [

potential race here perhaps

Seems to be temporary. I'm loading data as fast as I can into 2 vbuckets single node cluster.

Than few seconds later I'm getting


[ns_server:warn] [2012-06-07 12:26:37] [n_0@127.0.0.1:<0.5299.0>:compaction_daemon:do_chain_compactors:453] Compactor for vbucket `default/0` (pid [{type,vbucket}

this error also seems to be transient. I.e. next compaction actually succeeds.

attaching diags and will upload file (that's less than 4gigs)
