Hi,
We are using servicemix 3.2.2. We are facing couple of strange behavior
while load testing with camel's validator component.
1st Issue :
Sometimes in parallel request processing we are getting "Schema not
found error" from validation component. This behavior is not consistent it
just happens randomly with only parallel requests (with single request it
works fine). It gives following error :
ERROR - DeadLetterChannel - Failed delivery for exchangeId:
ID-esb-test1/42641-1219685726074/0-0. On delivery attempt: 0 caught:

3) the root element of the document is not .

2nd Issue :
Message flow:
Client --> HTTP consume SU --> Bean SU --> Camel Validation SU --> Camel
Routing SU --> HTTP Provider SU
In case I don't get above error then sometimes it just hangs after
processing some validation requests (parallel requests). By observing
JConsole we noticed that Live Threads count is almost constant but the
"Total Threads Started" count just climbs up. It went from 400 to more than
1100 within 3 minutes after this.

We have tried hitting around 60 parallel requests.
NOTE:- When we tried the same operation without validator component, we
are able to hit around 1000 parallel request without any issue. So it seems
that the issue lies with camel's validator component behavior in parallel
requests.
Does anybody experienced these kind of problems ?
Please provide your suggestions/help for the above issues.
Regards,
Rajesh
