   had many problems with the profiler. I found that modifying your mm.cfg was not neccacary and actually it was just my local security software.

   I posted a bit that fixes this issue if you are running ESET Smart Security.

   What software configuration do you have? Are you running windows/mac/linux. What firewall/anti-virus software do you use?

   While I try to run my Flex Profiler I got this error message:

   In the flash application I got the following exception:
   Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: file:///C|%2Fwork%2Flabsense%2Fbranches%2Frel%5F1%5F2%5F5%5FEA%2Fsources%2Fui%2F.metadata%2F.plugins%2Fcom.adobe.flash.profiler%2FProfilerAgent.swf?host=localhost&port=9999 cannot load data from localhost:9999.
   at ProfilerAgent()[C:\SVN\branches\3.2.0\modules\profiler3\as\ProfilerAgent.as:127]

   And in the flex Profiler console (at the eclipse) I got : Socket timeout.

   I am run on windows vista,
   Flex builder: 3.2
   Flash debugger : 10,0,22,87

   Things that I have done to resolve this issue:
   • Switch the connection port of the profiler to 9998 (and back)
   • Remove and reinstall the flash debugger player.
   • Install flex builder 3.2 (instead of 3.0)
   • Delete all the enters in the mm.cfg file
   • Add enter to the mm.cfg : PreloadSwf=C:\work\labsense\Sources\ui\.metadata\.plugins\com.adobe.flash.profiler\ProfilerAgent.swf?host=localhost&port=9999
   or
   PreloadSwf=C:\work\labsense\Sources\ui\.metadata\.plugins\com.adobe.flash.profiler\ProfilerAgent.swf?host=localhost&port=9998
   or
   PreloadSwf=C:/work/labsense/Sources/ui/.metadata/.plugins/com.adobe.flash.profiler/ProfilerAgent.swf?host=localhost&port=9999
   or with spaces:
   PreloadSwf=C: \ work \ labsense \ Sources \ ui \ .metadata \ .plugins \ com.adobe.flash.profiler \ ProfilerAgent.swf?host=localhost&port=9999
   or
   C:\work\labsense\Sources\ui\.metadata\.plugins\com.adobe.flash.profiler\ProfilerAgent.swf?
   or add all or some of the enters:
   TraceOutputFileName=C:\Users\zivo\AppData\Roaming\Macromedia\Flash Player\Logs\flashlog.txt
   ErrorReportingEnable=1
   MaxWarnings=0
   TraceOutputFileEnable=1
   ProfilingFileOutputEnable=1
   • Turn on and off the vista firewall
   • Add exception for port 9999 in the vista firewall
   • Try to run the profiler SWF separately

   Same result.

   Try one last thing:

   Because I have expreins problem little bit similar before with the flash debugger , the resolution then was :
   1. Right click on flash player (debugger),
   2. choose “Debugger”,
   3. choose “other machine”
   4. add “127.0.0.1”
   5. click ok
   then, it solve the issue (but apparently he connect to the debugger with host 127.0.0.1 instead of localhost (which is a same )
   I now add to the mm.cfg file, the follow entry:
   PreloadSwf=C:/work/labsense/branches/rel_1_2_5_EA/sources/ui/.metadata/.plugins/com.adobe.flash.profiler/ProfilerAgent.swf?host=127.0.0.1&port=9999
   Then, after saving , I run the profiler, and its work!!

   And the resonse for all this was :
   Some program change the file:
   C:\Windows\System32\drivers\etc\hosts
   To:
   # Copyright (c) 1993-2006 Microsoft Corp.
   #
   # This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
   #
   # This file contains the mappings of IP addresses to host names. Each
   # entry should be kept on an individual line. The IP address should
   # be placed in the first column followed by the corresponding host name.
   # The IP address and the host name should be separated by at least one
   # space.
   #
   # Additionally, comments (such as these) may be inserted on individual
   # lines or following the machine name denoted by a ‘#’ symbol.
   #
   # For example:
   #
   # 102.54.94.97 rhino.acme.com # source server
   # 38.25.63.10 x.acme.com # x client host

   ::1 localhost
   127.0.0.1 iDBO # LMS GENERATED LINE

   This means that localhost is not lead to 127.0.0.1!!!

   Fixing is easy :

   # ::1 localhost
   # 127.0.0.1 iDBO # LMS GENERATED LINE
   127.0.0.1 localhost

   Instead (remark the problem and fix the problem

   Thenks

   This is my mm.cfg
   ErrorReportingEnable=1
   TraceOutputFileEnable=1
   MaxWarnings=0
   ProfilingOutputFileEnable=1
   ProfilingOutputDirectory=C:\flex\profiling
   TraceOutputFileName=C:\flex\Logs\flashlog.txt
   PreloadSwf=D:\WORK\WorkVW\.metadata\.plugins\com.adobe.flash.profiler\ProfilerAgent.swf?host=localhost&port=9999
   FrameProfilingEnable=0
   ProfileFunctionEnable=0

   I use eclipse plugin so in the preferences i set the profile port to 9999

   Try setting debug to true in the mm.cfg file so something like:

   PreloadSwf=/Users/[username]/Documents/workspace/
   .metadata/.plugins/com.adobe.flash.profiler/
   ProfilerAgent.swf?host=localhost&port=9999&debug=true
