I'm not sure if this has already been officially announced, but i've heard rumors that we're going to increase the minimum required memory for UTM9 to 2GB, because some of the new features. On the other hand, it's no news that especially IPS already is very memory intensive.
No after a reboot it's all normal. I had this phenomen only twice after I played around with clientless VPN. Now I have 2GB more Memory assigned to the VM to prevent this failure. The phenomen is at the moment away...
