Since I have upgraded to 3.2.2.2, I sometime receive these messages:

May 07, 2009, 07:06:00 Session 0: Connection from 208.76.244.82 accepted on 10.0.43.50:25
May 07, 2009, 07:06:00 Session 0: (connect) No buffer space available

After that, the SMTP service no longer works and I have to restart the Windows service.

What may cause this?

Thank you for your support.

This happens when the operating system returns an WSAENOBUFS (10055) error. This can happen for a number of reasons, depending on the Windows version and service pack you use.

There are several web pages and MS knowledge base articles dedicated to this error message, just google WSAENOBUFS to get started.
