BD memory increases. May reach a kernel 'OOM killer' scenario.


High memory consumption on the system, swap memory usage, potential crashes.


Usually a policy with missing content profiles (XML, etc.) on a post request that causes the POST to be parsed incorrectly and issue many parameter violations.


Apply the correct content profiles. Note: Valid requests typically do not have that many parameters in them. If you have requests that do, apply the 'apply value signature' on those big POSTs.
