mailspool.CS.Berkeley.EDU was not accepting incoming email

mailspool.CS.Berkeley.EDU was not accepting incoming email from Thursday February 5, 2009 02:56 to 05:30.

This resulted in delay of delivery of email. No email was lost. No warning messages should have been sent back to senders.

It appears the process table on mailspool.CS.Berkeley.EDU became full. It appears this may have been a ddos attack.

mailspool.CS.Berkeley.EDU was rebooted to resume normal service.
