Daniel Kulp commented on CXF-5912:
----------------------------------
Two things that may help:
1) Upgrade to a newer version of CXF
2) Make sure you are using Woodstox (and the most recent versions as well), not
IBM's StAX parser
There are a lot of other OOM errors and other attacks that can easily occur if
you don't do both of the above.

> Hi,
> When dealing with big files (10MB or more) in Base64 an OutOfMemory exception
> is created, even when the server has enough memory to load it.
> We would like to know if another treatment is possible to avoid the full
> message from being loaded into memory during unmarshalling.
> For instance when sending files in MTOM (900MB) no memory issue arise because
> they are streamed through disc.
> So far we have seen that this error happends because the full message is sent
> to Stax parser without any pre-treatment.
