I have the same problem (virtual machine), PLE values:

393

393

4294925

4294940

4294956

440

I solve the problem with this powershell script:

$server = "Server1"

& relog Server1_XXXX.blg -f csv -o logfile.csv

($csv = Import-Csv logfile.csv -Delimiter ',') | ForEach-Object{

if([convert]::ToInt32($_."\\$server\SQLServer:Buffer Manager\Page life expectancy", 10) -gt 100000)

{

$_."\\$server\SQLServer:Buffer Manager\Page life expectancy" = 1000

}

}

$csv | Export-Csv logfile_fixed.csv -Delimiter ',' -NoType
