Hi,
We are using servicemix 3.2.2. We are facing a strange behavior while
load testing with camel's validator component.
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:
org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema
document
'file:/home/ofbiz/apache-servicemix-3.2.2/data/smx/service-assemblies/changepassword-sa/version_1/sus/servicemix-camel/validate-su/updatepassword.xsd',
because 1) could not find the document; 2) the document could not be read;
3) the root element of the document is not <xsd:schema>.

Why this shows random behavior ?
Is there any solution or workaround to resolve this issue ?
