Description:
Process Microsoft.Exchange.RpcClientAccess.Service.exe (PID=5396). User 'Sid~ADS\ArchiveMGR_ESM~RCA~false' has gone over budget '635' times for component 'RCA' within a one minute period. Info: 'Policy:DefaultThrottlingPolicy_06b501c2-211e-4c4c-baf2-962a1c6a8af5, Parts:CAS:634;'. Threshold value: '100'. -
Resolution
Exchange 2010 has a default throttling policy, limiting the number of RPC connections an account can make to the CAS server. Since the ESM service creates numerous threads it can exceed the default throttling policy.
As per Understanding Client Throttling Policies, create a new throttling policy that has no limit specified for simultaneous MAPI calls to Exchange servers, and assign this policy to the ArchiveMgr_ESM service account.
To create a new throttling policy and assign it, do the following:
1. Logon to a 2010 Exchange Server - Open Exchange Management Shell.
2. Type the following commands:a) New-ThrottlingPolicy AMPolicy
b) Set-ThrottlingPolicy AMPolicy -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null
c) Set-throttlingPolicyAssociation "ArchiveMgr_ESM" -ThrottlingPolicy AMPolicy
