SIP Traffic - End Reason Resources Unavailable

[Jatin.Singh]

We seem to have a lot of SIP traffic that is reporting a Session End Reason of "resources-unavailable".  This traffic is hitting rules that don't even match.  Please refer to attached screen capture. What could be the reason?

Thanks for your assistance,

resources-unavailable

The session dropped because of a system resource limitation. For example, the session could have exceeded the number of out-of-order packets allowed per flow or the global out-of-order packet queue.

We are having the same exact issue, did you get it resolved? Thank you.
