i'm running openvz on ubtunu Lucid (kernel 2.6.32.28-openvz-pae). the templates i used are ubuntu 10.04 ones.

i tried to upgarde one of my two VEs from 10.04 to 10.10.

The process was broken (the upgrade didn't finished. I googled and found some solutions ( https://forum.ramhost.us/bbs/viewtopic.php?id=330 ) to finish the upgrade but my VE still hungs after few hours of a restart because of lake of memory.

any shell commands returns: "-bash: fork: Cannot allocate memory"

Any suggestion?

Thank you in advance
