In your case, I think you are trying to put or get huge objects, that contain internal collections and so on. > at > o.a.i.i.binary.BinaryUtils.doReadCollection(BinaryUtils.java:2016) > at > o.a.i.i.binary.BinaryReaderExImpl.deserialize0(BinaryReaderExImpl.java:1904) ... > at > o.a.i.i.binary.BinaryUtils.doReadCollection(BinaryUtils.java:2016) > at > o.a.i.i.binary.BinaryReaderExImpl.deserialize0(BinaryReaderExImpl.java:1904) Another possible reason is intensive use of getAll()/putAll() methods from different threads. In that case, you need to sort collection of keys before, because batch operation on the same entries in different order could lead to deadlock.
