Access Denied to SharePoint 2010 site collection administrator

We have an issue with SharePoint. We did content deployment from one Environment to another. After that it says Access Denied for me, even though am site collection administrator

Below is the troubleshooting steps performed.

I have Delete the web application and recreated (but not the content database)

I have Recreate the web application and reattach the content database(s)

I have IISRESET for good measure

I have checked in "Site collection Quotas and Locks option".

                -Set-SPSite -Identity "http://site:88" -LockState "Unlock"

I have changed the account for the APP Pool was running on IIS.

I have used managed account to perform the content deployment activity

I have added myself DB_owber to this particular site DB (SQL front)

Solution:

Sharepoint server Failed to read the acls for an item.Hence we need to run the following command from Sharepoint 2010 management Shell:

$webApp = Get-SPWebApplication http://Site:9999

$webApp.GrantAccessToProcessIdentity("Domain\serviceac")
