Does IISnode timeout the Http Request

[gwadhwa]

I see Http 500 error when server takes more than 30 sec to respond.

I checked all the properties in IIS but seems no issue.

Please help.

You need to use these settings
<attribute name="maxNamedPipeConnectionRetry" type="uint" defaultValue="100"/>
<attribute name="namedPipeConnectionRetryDelay" type="uint" defaultValue="250"/>

Here is my settings....still getting Error when response cross 30 seconds.

iisnode node_env="development" asyncCompletionThreadCount="0" nodeProcessCountPerApplication="1" nodeProcessCommandLine="%programfiles%\nodejs\node.exe" interceptor=""%programfiles%\iisnode\interceptor.js"" maxConcurrentRequestsPerProcess="1024" maxNamedPipeConnectionRetry="100" namedPipeConnectionRetryDelay="150" maxNamedPipeConnectionPoolSize="512" maxNamedPipePooledConnectionAge="300000" initialRequestBufferSize="100096" maxRequestBufferSize="6553600" uncFileChangesPollingInterval="5000" gracefulShutdownTimeout="60000" debuggingEnabled="false" debuggerPathSegment="debug" debuggerPortRange="5058-6058" maxLogFileSizeInKB="128" loggingEnabled="false" devErrorsEnabled="false" flushResponse="false" watchedFiles="*.js" promoteServerVars="APP_POOL_ID,UNMAPPED_REMOTE_USER,LOGON_USER,HTTP_VERSION,REMOTE_PORT,REMOTE_ADDR,REMOTE_HOST,LOCAL_ADDR,AUTH_USER,AUTH_TYPE,SERVER_PORT,APPL_PHYSICAL_PATH,CONTENT_TYPE,HTTP_HOST,HTTP_METHOD,HTTP_USER_AGENT"

windows status from IIS log is 500.0 109
which means pipe has been ended.

Please help!.

[rramachand21-zz]

you have set maxNamedPipeConnectionRetry="100" namedPipeConnectionRetryDelay="150" .. this means your timeout would be 15000 millseconds or 15 seconds.

[gwadhwa]

Moved to
maxNamedPipeConnectionRetry="1000" namedPipeConnectionRetryDelay="150"

means 150 seconds... Still same error..

Any help is much appreciated...

more detail scenario: posting a 100 MB data from client to server. it seems IIS node does not pass this request to node.exe. What I see is HTTP 500 error from IIS. sub status code is 109 which means pipe has been ended.

Why iisnode does not pass this request to node.exe, increased timeout as I mentioned above but nothing worked.

Please help!.

Hi,
Were you able to figure out a solution for this? I am stuck in a similar situation!

[gwadhwa]

Use the above to increase timout.
We added nodeProcessCommandLine="%programfiles%\nodejs\node.exe --max_old_space_size=8000"

thats fixed the issue.

I am also facing similar issue. Trying to download data close to 350 MB. Below is my webconfig. Please suggest.

  nodeProcessCountPerApplication="1"
  maxConcurrentRequestsPerProcess="1024"
  maxNamedPipeConnectionRetry="10000"
  namedPipeConnectionRetryDelay="250"      
  maxNamedPipeConnectionPoolSize="512"
  maxNamedPipePooledConnectionAge="30000"
  initialRequestBufferSize="100096" 
  maxRequestBufferSize="6553600"      
  nodeProcessCommandLine="%programfiles%\nodejs\node.exe --max_old_space_size=8000"
