soap - wso2 ESB request is truncated -

i'm using fresh installation of wso2 esb 4.8.1 stanalone default configuration. when send soap request backend (perl service soap lite), body of post request truncated according tcpdump:

soapaction:      "" content-type:    text/xml content-length:  511 host:            192.168.11.234:8181 connection:      keep-alive user-agent:      synapse-pt-httpcomponents-nio  <?xml version="1.0" encoding="utf-8"?><soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="htt p://www.w3.org/2001/xmlschema" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance">   <soap:body>     <deleteaccountforhost xmlns="abcdehostingphysicalhostmanagercpanelservice">    <host xsi:type="xsd:string">zs000.abcde.net</host>    <user xsi:type="xsd:string">tstauto</user> </deleteaccountforhost>   </soap:body> </soap:envel 

you can see closing tag '</soap:envel' truncated.

but when enable soap-tracer request body becomes valid. use pt transport. tried switch transport nhttp , problem seems disappeared.

so question is: how configure pt transport avoid such strange behavior?

upd1: seems problem occurs when set property force_http_1.0 , transport pt

i got same problem, set disable_chunking.

after many tries tested disabling chunking or forcing http 1.0 results in truncated request.

i use wso2 esb version 4.8.1, client soapui 5.0.0 or soapclient php 5.5.11.

when use "try service" in esb, request not truncated.

after switching http passthrough transport http-nio transport service behind endpoint receives complete request, can't download wsdl of tenant.
