Disable poolMember Exception

I met the similar issue and didn't find the answer from devcentral. anyone can help?

BIG-IP version: BIG-IP 11.3.0 Build 3164.27 Engineering Hotfix HF10 Powershell version:

Name : Windows PowerShell ISE Host Version : 2.0

script

==== Write-Host "Waiting for current connections to drop to zero..." $MemberDef = New-Object -TypeName iControl.CommonIPPortDefinition; $MemberDef.address = $member_addr; $MemberDef.port = $member_port;

$MemberDefAofA = New-Object -TypeName "iControl.CommonIPPortDefinition[][]" 1,1 $MemberDefAofA[0][0] = $MemberDef;

$cur_connections = 1;

while ( $cur_connections -gt 0 ) { $MemberStatisticsA = (Get-F5.iControl).LocalLBPoolMember.get_statistics( (, $pool_name), $MemberDefAofA); $MemberStatisticEntry = $MemberStatisticsA[0].statistics[0]; $Statistics = $MemberStatisticEntry.statistics; foreach ($Statistic in $Statistics) { $type = $Statistic.type; $value = $Statistic.value;

  if ( $type -eq "STATISTIC_SERVER_SIDE_CURRENT_CONNECTIONS" )
  {
     just use the low value.  Odds are there aren't over 2^32 current connections.
     If your site is this big, you'll have to convert this to a 64 bit number.
    $cur_connections = $value.low;
    Write-Host "Current Connections: $cur_connections"
  }
}
Start-Sleep -s 1

}
