PowerShell remote invocation mysteriously hangs -

i have created series of functions collect iis configurations site, when run on server locally executes without issue (albeit slowly) when run them remotely using invoke-command in powershell 2 runs through , mysteriously stops approximately 15-20 seconds process. stalls on same request not always. same commands executed locally work without issues. no exception raised, hangs indefinitely.

i can post code if necessary several hundred lines i'm more looking guidance on how investigate problem or if has encountered similar.

sometimes makes 15 or so. tried laptop , 1 server , behavior same.

here loop hanging:

$start = [system.datetime]::now $numanalyzed = 0 if ($true) #skip test { # loop through physical folders faster foreach ($folder in $folders) {      write-host $numanalyzed $folder.fullname     #figure out virtual path folder     $iis7vwebfolderpath = $folder.fullname.replace($iis7webapp.physicalpath, $iis7vdirwebapppath)     #get-item $iis7vwebfolderpath | gm     $iis7vwebdirconfigitem = get-lnosiis7configforpspath -pspath $iis7vwebfolderpath      # add new item list     $iis7vwebdirconfig += $iis7vwebdirconfigitem      # increment counter , report out progress every 10     $numanalyzed++     if ($numanalyzed % 10 -eq 0)      {         $end = [system.datetime]::now        $timesofar = (new-timespan –start $start –end $end).totalseconds        $timeremaining = ($folders.count - $numanalyzed) * ($timesofar / $numanalyzed)        "analyzed {0} far... took {1} seconds, remaining time {2} seconds" -f $numanalyzed,$timesofar,$timeremaining  | write-host         "current folder: {0}" -f $folder.fullname | write-host     } } }    $end = [system.datetime]::now "processed web dirs: {0} took {1} seconds" -f $iis7vwebdirconfig.count,(new-timespan –start $start –end $end).totalseconds | write-host   | write-host 

the function i'm having performance problems , i've got separate question post has source code function:

web-administration vs wmi query web directory properties performance problems

i think may have discovered problem, started getting odd failures in other parts of script:

 [severname] processing data remote server servername failed following error message: wsman provider host process did not return proper response.  provider in host process may have behaved improperly. more information, see about_remote_troubleshooting topic.   + categoryinfo          : openerror: (servername:string) [], psremotingtransportexception  + fullyqualifiederrorid : 1726,pssessionstatebroken 

and

processing data remote command failed following error message: not enough storage available complete operation. more information, see about_remote_troubleshooting topic. + categoryinfo          : operationstopped (system.manageme...pressionsyncjob:psinvokeexpressionsyncjob) [], psremotingtransportexception + fullyqualifiederrorid : jobfailure 

this lead me following site: http://www.gsx.com/blog/bid/83018/troubleshooting-unknown-powershell-error-messages

the following recommendations seems have cleared of problems although still have testing do.

excerpt site below:

as first error message specifies, overflow of memory in remote session has occurred. open powershell prompt on remote server , display configuration of winrs using:

winrm winrm/config/winrs 

check "maxmemorypershellmb" value. set default 150 mb on windows server 2008 r2 , windows 7. microsoft changed in windows server 2012 , windows 8 1024 mb.

in order resolve issue, need increase value @ least 512 mb following command:

winrm set winrm/config/winrs `@`{maxmemorypershellmb=`"512`"`}
