Good suggestion, thank you. Unfortunately the machine in question is a VPS.

RAM issues are usually indicated by "bad alloc" in either the bitcoin or the systems log files.

Edit: I wrote this small bash script to see whether the high memory usage was related to the spam attack:

Code:

#!/bin/bash

date="$(date +%F-%R)" #current date and time
sizebytes="$(bitcoin-cli getmempoolinfo | grep [size,bytes] | egrep -o [0-9]*)"
usedfree="$(free -m | grep "^-/+" | egrep -o [0-9]*)"
mem=()
while read -r line; do
mem+=("$line")
done <<< "$usedfree"
#echo "${mem[0]}|${mem[1]}"
txp=()
while read -r lines; do
txp+=("$lines")
done <<< "$sizebytes"
echo "$date|${txp[0]}|${txp[1]}|${mem[0]}|${mem[1]}" >> badalloc.log

I also add a header every 24 hours.

Code:

Sample output for today:
