These are just warnings about lock contention, but you should probably 
switch from Berkeley DB to skiplist for your mailboxdb.  The setrlimit 
failure is just warning you that it was unable to set unlimited file 
descriptors, but unless you have 1000 simultaneous connections you don't 
need to worry about it.
