When we get junk data as an XML-RPC request we try to log that request, assumingly to aid in debugging. However that request can be rather large as we allow up to 1 MiB of data. We should probably limit things to something sensible in such cases.
This can happen in two places:
1. When parsing the incoming request (see bug 5032)
2. When parsing the response (logs "Trouble parsing XMLRPC response from VSM Agent ...")
