----------------------------------------
Summary: Handling concurrent Base64 files causes memory overflow
Key: CXF-6219
URL: https://issues.apache.org/jira/browse/CXF-6219
Project: CXF
Issue Type: Improvement
Components: Soap Binding, WS-* Components
Affects Versions: 2.7.4
Environment: Production
Reporter: Abel Salgado Romero
In a previous issue (https://issues.apache.org/jira/browse/CXF-5912) we were
advised to update CXF version to avoid OOM errors.
We did so (to 2.74) and the problem was fixed, we also applied a size limit of
20MB using the `org.apache.cxf.stax.maxTextLength` property.
However, the memory consumption in the server is extremely higher than the
actual data sent, having 1GB of Heap we get OOM sending just 6 concurrent
requests of 20 MB.
Reviewing some documents and other JIRA issues, we understand that Base64 is
not optimized and not recomended. Can you confirm if this is the case or if
there is a way to optimize how Base64 attachments are processed.
Otoh, MTOM works like a charm ;)
