      Summary

      iwp returns error 500 when connecting for auth

      Product

      FileMaker Server

      Version

      11.0.4.404

      Operating system version

      OSX Server 10.6.8

      Description of the issue

      Recently (last 2-3 months), we've been  encountering an issue whereby users attempting to connect to the Web Publishing interface ( /fmi/iwp/res/iwp_home.html ) receive a blank screen (except for the FileMaker header); otherwise expecting login dialog

      In all cases, it's the same error in the logs:

      /var/log/apache2/access_log:
      > 17.205.xx.xx - - [06/Jul/2012:15:16:40 -0700] "GET /fmi/iwp/cgi?-dblinks HTTP/1.1" 500 9940

      /Library/FileMaker Server/Logs/pe_application_log.txt:
      > 2012-07-06 15:16:40 -0700 FM Web Publishing - - wpc1 Error: 500

      without any other context I could discern when comparing to working sessions. The issue exists in both Safari and Firefox, cleared cache, restarted, turning if off and back on again, etc ... Strangely the issue persists for a particular person for around 10-15min or switching browsers (Safari <-> Firefox), after which it starts working .. meanwhile, it's broken for someone else.

      Rebooted server, upgraded to latest everything (latest version 11), check memory, file descriptors and even dtrace'd the "FM Web Publishing" process but couldn't find a difference between working/non-working.

      Only the Web Publishing function is having an issue ... the native client interface otherwise appears to be working fine.

      Steps to reproduce the problem

      Connect to /fmi/iwp/res/iwp_home.html URL

      Expected result

      Receive a login screen

      Actual result

      Blank page except for banner at top

      Exact text of any error message(s) that appear

      /var/log/apache2/access_log:
      > 17.205.xx.xx - - [06/Jul/2012:15:16:40 -0700] "GET /fmi/iwp/cgi?-dblinks HTTP/1.1" 500 9940

      /Library/FileMaker Server/Logs/pe_application_log.txt:
      > 2012-07-06 15:16:40 -0700 FM Web Publishing - - wpc1 Error: 500

      Configuration information

      OSX Server 10.6.8
      12GB RAM (no memory deficit)
      2.26Ghz quad-core Xeon
      max open files == 10240
      daily backup 11:30pm (no hourlys)
      max sessions == 100 (never close to this)
      file maker accounts only
      6 databases, but only 1 (fairly small) database active
      no plugins
      session timeout 15min

      Workaround

      Usually wait 10-15min or switch browsers or computers -- has been less effective
