Hi I'm brand new to MINA. I've come up with a protocol which includes file attachments. I'm extending the CumulativeProtocolDecoder as per the ImageDecoder example in the documentation. It works fine for small files but I am unable to send a 1.5MB file, it never gets further than around 320 - 330k (varies every time). Without going into too much further detail, here are some log excerpts from my application. I log every time I enter doDecode and return false in doDecode():

I run this with 1GB heap size and 256M max direct buffer size. Does anyone have any insights? Thanks Peter
