have you actaully checked your heap space? -Xmx does not specify which pool the memory goes to, you're going to need more parameters than that.
keep in mind 750mb is just the object once in memory, when you create the soap message it may duplicate the bytes, and if it does a base4encoding on it, it may tripple in size so you might need to ensure your smallest memory pool is close to 3g or 4g... given it splits the memory pools into different parts, I'm not convinced your -Xmx6g is enough... I must say 750mb soap payload is quite impressively large. On 6/19/13, shamikb <[email protected]> wrote: > Hi, > > I'm struggling to read a large file transmitted through a SOAP based web > service.
