As the title says, I updated my node from version 3.0.1 to 5.0.0 today, and it is not synchronizing. It initially started to sync and it would not work. I rebooted my virtual server, tried again, and it successfully started to sync 300 blocks and updated 3 days worth, then stopped. I rebooted my virtual machine again, but it is still stuck. I am getting the following message in my terminal window…

The daemon will start synchronizing with the network. This may take a long time to complete.

You can set the level of process detailization through “set\_log \<level|categories\>” command,  
where is between 0 (no details) and 4 (very verbose), or custom category based levels (eg, \*:WARNING).

Use the “help” command to see the list of available commands.  
Use "help " to see a command’s documentation.

Couldn’t allocate RandomX cache

What does “Couldn’t allocate RandomX cache” mean? How can I resolve this?  
I’ve been hosting a node for everyone since our mainnet started, and I’d like to keep up with it. Any help would be much appreciated.

At first glance, how much memory do you have allocated to the virtual machine?

It could have to do with not having enough RAM

It is a basic Vultr account 512MB of ram, 20GB of storage, and running ubuntu 18.04. Same VS I setup over a year ago when mainnet first started.

EDIT:  
I tried upgrading my VS ram from 512MB to 1024MB. Ran safexd again and it is synchronizing now. Thanks!
