caused by: System.DmlException: Update failed. First exception on row 0 with id 0018000001AKu9XAAT; first eror: UNABLE_TrO_LOCK_ROW, unable to obtain exclusive access to this record or 1 records: 0018000001AKu9XAAT: []

I received the following error message and researched on the forms and the solution seems to be adding UPDATE FOR but I couldnt make that update in SOQL query as I received an error message "Cannot lock rows for an SObject type that can not be updated: AggregateResult"

So im not sure if I need to edit the code where I call List<Account> to an SOQL statement.  See my code below.

Hi Justin,

There might be the batch process running along with this trigger.

change your batch that is holding the account records that are queried in your trigger, 
do one thing make sure that batch size is less and trigger shouldn't run behind this batch 

modified your logic.

Correct me if I am wrong.

Thank you,

                                                 FROM Case 
                                                 WHERE Id IN :Trigger.newmap.keySet()
                                                 AND 
                                                 AccountId <> null
                                                 AND Severity__c IN ('Blocker','Critical','Major')
                                                 Group By AccountId
                                                 ];

        List<Account> accountsToUPdate3 = new List<Account>();

        for(AggregateResult contactAggr : contactAggrList) {
            accountsToUPdate3.add(new Account(Id = (Id)contactAggr.get('AccountId'),
                                             Issue_Score__c = (Decimal)contactAggr.get('expr0'))); 

        }

        update accountsToUPdate3;
