 2.6.37.6-2 on the other hand has other bad behaviour, like two vservers 
 sending to each other lots of concurrent http connections, made apache 
 processes stall in D state (mostly the main watcher), lots of Z and port 
 80 unresponsive for several minutes, when it just recovered.

 actually the http connections were coming off the internet, same 
 "lockup" was noticed, so far had to downgrade to 2.6.36.2-1 kernel and 
 sudo-1.7.4p6-1.i686 to continue normal work
