I guess you installed the OS-Update 3.0! :)

You have to install more memory... It seems the configuration of sendmail
is a lot harder on memory usage, I haven't looke into it, just seen this
happen to both qube and raq2 with the latest update.

Either change into a new server with more memory or upgrade the memory of
the server or find the settings in sendmail.cf to turn off this behaviour.
