sockets - Jmeter Error: Java.net.SocketException: Connection reset at java.net.SocketInputStream.read(Unknown Source) at -

-

jmeter environment details performing jmeter testing on microsoft azure cloud. have created on vm(virtual machine) on same cloud , there hitting application server on same cloud environment. in case there no network latency.

problem statement: trying run load test 300 users 30 mins , after 5 mins script started failing, because of socket connection refused error.

my analysis based on information available on net:

i have read somewhere problem because of limited socket connection limit on server, when run same test vm scripts run's fine. not server's issue. can please me resolve issue? there settings needs done in jmeter, increase socket connections?

actual screenshot of error enter image description here

most likely:

looks situation described @ connection reset since jmeter 2.10 ? wiki page. if you're absolutely sure nothing wrong server, can follow next recommendations:

  1. switch http request samplers "implementation" "httpclient4". fastest , easiest way of doing using http request defaults.

  2. add next lines user.properties file (in jmeter's /bin folder)

    httpclient4.retrycount=1 hc.parameters.file=hc.parameters

  3. add (or uncomment , edit) following line in hc.parameters file

    http.connection.stalecheck$boolean=true

alternative assumption:

"good" browsers send "connection: close" last request web server. "bad" browsers don't , keep connection open. can control behaviour via "use keepalive" checkbox in http request sampler/defaults. if it's unchecked - can try ticking it.

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
