Ive just done a fresh install and im having abit of issues with mailbox crashing. From experiment, i can see that zimbra crashes when i play around with zimbraAdmin console alot i.e logging in logging off, navigating between different sections of zimbraAdmin. I notice sometimes that there is a huge delay clicking between different menus, maybe the server is doing some processing im not sure. My system is currently running 1GB of memory. Can this be the only reason for this problem?
