And can u show me the config file? First part only
shoud I reboot ubuntu?
Type:
top
How is the cpu/mem ?
CPU usage suddenly going upward, keep climbing up
Try to restart the server… but in the Producer do u see tx?
Producer , yes I see TX increasing. Ok, I will reboot the server.
Will let you know when I am up again
Could it be possible someone hacking the machine? I rebooted an no effect.
I look at the cpu usage of producer node , it is only 3.25%, on the relay, it is 65 %,
How can I tell if something is happening or it is normal cardano relay activities
What is the hw configuration?
Go in config file and set TraceMempool to false
Machine is back. Here is the config.json

yes, server is back, there is no TraceMemPool variable for me to set. Should I show you the whole confi.json?
But… line 36 from above? 
oh, sorry about that, I did a search and didn’t see, maybe machine too slow.
Now the server become slow again, looks like some program is running on it…
This is after reboot already, now it become slow again.
Relay Node is the only program running on it … Do you have any suggestion?
What is the hw configuration? Try to set the TraceMempool to false and restart the node
I just change the TraceMemPool to False, and save and restart the cardano node,
Hw is 4G of memory and 30 G storage.
Ooo. With 4g ram and 30 g space… it’s almost at limit…
Sorry , it is4G of ram and 2 CPU, so do you mean is too small for the relay node? on producer node the usage is only 3.25%
3,25% ? My nodes are using 3,2g ram
I am double check from command line, is this the command to check?
grep MemTotal /proc/meminfo | awk '{print $2 / 1024}'
I am trying to see if there is a way to increase memory size on AWS ubuntu instances
I just change the TraceMemPool to false and reboot 19 mins now, the produced TX is still 0,
what else should I check or just wait?
