OpenSAML user discussion

["Singh, Manish" <>]

As I mentioned sometime back, we have executed a load test against the
OpenSAML code that we have in place for SP implementation.

I see below exception in log occasionally. It's not frequent but still
there are more than a few occurrence during a few hours test.
I did not see the below error while manually testing the connection.

I looked at the encrypted Assertion we are receiving (from PingIdentity)
but did not find anything alarming.

Any help in understanding the cause of below error is appreciated.

I have set maxPoolSize for BasicParserPool to 10
And createBuildersAtPoolLimit = true
setNamespaceAware = true

I am also curious to know what does "FWK005" means below.

Thanks,
Manish
