Checking memory usage?

Server seems to go down after 9 hours uptime. Can you let me know a command to output the resource usage to a log file or just manually check?

After doing find memory in console I noticed these

pool.clear_memory( )

pool.print_memory( )

 

Ah I see.

It's a shame, my server would stay up until I'd manually restart it just a few weeks ago, would be running fine even with 3 days of uptime. Seemed to go downhill since the Unity downgrade.
