Hi, what changed between version 1.4.2 and 1.5.2 was the addition of the application level flow control mechanism which changed a bit how the network buffers are configured. This could be a potential culprit.
Since you said that the container ran for some time, I'm wondering whether there is somewhere a resource leak. In order to debug this, the heap dump would be tremendously helpful.
