Hi Easy,

I guess the problem has been fixed in the 7.8 snapshot. Could you please give it a try and report back?

Best,
Christian

Hi，all，
I have a web service as fellow :

declare

  %output:method("xml")

  %output:omit-xml-declaration("no")

  %output:media-type("application/xml")

  %updating

  %rest:path("/add_ehr_doc")

  %rest:POST("{$body}")

  %rest:header-param("pid","{$pid}")

  %rest:header-param("doc_id","{$doc_id}")

  %rest:header-param("op","{$op}","APND")

 function ehr:add_ehr_doc(

   $body ,$pid as xs:string,$doc_id as xs:string,$op as xs:string

 )

  {

    (:let $state:=db:open($ehr:dbname):)

    (:let $path:=if(string-length($pid)>=15 and string-length($pid)<=18) then

        substring($pid,1,6)||'/'||substring($pid,7,8)||'/'||substring($pid,15)||

      else

        $pid:)

    let $fp:=substring($pid,1,6)||'/'||substring($pid,7,8)||'/'||substring($pid,15)||'.xml'

    return

    if (db:exists($ehr:dbname,$fp)) then

       (

         insert node ($body//*:DataSet) into (doc($ehr:dbname||"/"||$fp)//*:BasicDataset),db:output(<msg>

ppend</Ack><Url>{$fp}</Url></msg>)          )

   else

     (    db:add($ehr:dbname, $body,$fp),db:output(<msg><Ack>201 new add</Ack><Url>{$fp}</Url></msg>)

       )

 };

then there is a process call the service continuously. some times, will occur this error.
