What do you mean with "haproxy completely hangs" ? Do you mean it spins at 100% CPU, freezes, or something like this, and that you have to restart it ? The request below looks completely normal : > POST /mtn/zm/consumer/register HTTP/1.1 > Authorization: Basic YWZiYmFuazpFFmMxMjl0NTYh > Content-Length: 1049 > Content-Type: text/xml; charset=UTF-8 > Host: 172.31.6.24:8000 > Connection: Keep-Alive > User-Agent: Apache-HttpClient/4.2.3 (java 1.5) (...) so does the body : > <?xml version="1.0" encoding="UTF-8" standalone="yes"?> > <ns2:customerregistrationrequest > xmlns:ns2="http://www.ericsson.com/em/emm/sp/backend"; > xmlns:ns3="http://www.ericsson.com/em/emm/sp/frontend";> > <resource>FRI:260969524530/MSISDN</resource> > <name> > <firstname>Andrea</firstname> > <lastname>Oxenham</lastname> > </name> > <gender>FEMA</gender> > <dob>1989-10-07</dob> > <idtype>PASS</idtype> > <idnumber>1ABCD1</idnumber> > <idexpiry>2026-10-16</idexpiry> > <language>en</language> > <addresses> > <address> > <AdrTp>HOME</AdrTp> > <MlngInd>false</MlngInd> > <RegnAdrInd>false</RegnAdrInd> > <NmAndAdr> > <Adr> > <AdrLine>Lusaka</AdrLine> > <PstCd>LUSAKA</PstCd> > <TwnNm>Lusaka</TwnNm> > <CtrySubDvsn>LUSAKA</CtrySubDvsn> > <Ctry>ZM</Ctry> > </Adr> > </NmAndAdr> > </address> > </addresses> > </ns2:customerregistrationrequest> > > > Of interest to note is the newline at the end of the body, that???s what > makes the content-length add up to 1049, is there any reason why this request > is being dropped.? No there is no such reason. HAProxy takes the routing decision once it gets the whole headers, so even if the request was too short or too long, it would forward what it already has. Is only this request blocked or do you observe the same issue with different requests as well ? You didn't tell us what version you're running nor provided your config. Maybe you're hitting an old well-known bug ? Please send the output of "haproxy -vv". Regards, Willy
