Hello,
im not able to receive md5 hash on big files (1.5GB) via scriptblock.

$blok = {

function get-hash
{
 $md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider
 return $hash = [System.BitConverter]::ToString($md5.ComputeHash([System.IO.File]::ReadAllBytes($_.fullname)))
}
get-childitem f:\data_protector_7_0 -Recurse -force |?{!$_.Psiscontainer}| select fullname ,@{n="Hash";e={$_ |get-hash}}
}

I receive only Fullname, hash property is empty

FullName : F:\data_protector_7_0\ESD_HP_DP_7.00_for_Windows_TD586-15003.01.zip
Hash     :

When I run the code locally on server, it works fine

The code itself is working remotely, I can receive hash keys on other files with no problem

Only have issue with these big files.  Its like getting OutOfMemory exception without any error.

Same issue occur, when I run the code via enter-pssession ... still not working on these big files.

I need to check validity on some ZIP files.

Server1: (good)

Well, 16GB on remote session is quite OK for a file server.

And yet, the script was working fine (no obvious errors in the script, because it is working for smaller files... please)

Why should i increase RAM on remote server, when i can run this script directly on remote server, but cannot do it via PSSession?  Does remoting have increased memory requirements or what?

winrm get winrm/config/winrs
Winrs
    MaxMemoryPerShellMB = 150
winrm set winrm/config/winrs `@`{MaxMemoryPerShellMB=`"2048`"`}
Winrs
    MaxMemoryPerShellMB = 2048

Script is working fine now. Thx Jrv
