this is a trigger that i made which every time an email is sent and the mail2case create a case out of it the trigger is run and change the case "last modified" field

the problem is sometimes i get the "Too many SOQL queries :21" Error

this is the trigger code :

trigger Task_1 on Task (after insert)

{

Task task = trigger.new[0];

if(task.WhatId != null)

{

if(Util.getObjectType(task.WhatId) == 'Case' && Util.getTaskType(task.Subject) == 'email')

{

Case c = [select Id, Subject,OwnerId from Case where Id =: task.WhatId];

List<Task> t = [Select t.WhatId, t.Subject From Task t Where t.WhatId = :c.Id];

for(Integer i=0;i<t.size();i++)

{

if(Util.getTaskType(t[i].Subject) != 'email')

{

t.Remove(i);

}

}

if(t.size()>1)

update c;

}

}

}
