please check below post
1) http://salesforce.stackexchange.com/questions/53112/maximum-view-state-size-limit-135kb-exceeded
2) http://forceguru.blogspot.in/2012/12/uploading-multiple-attachments-into.html

Try to make Attachment as Transient or create file uploade variable like below
public Transient Blob resume {get; set;}

Transient variables are not stored in the view state, but can be regenerated by the post back if bound to an input element. In general, you only need to use the view state for elements not bound to an input element and need to maintain state between post backs.

Please let us know if this will help you

Thanks
