Hi there! We are trying to run full-node on AWS EC2 r5.large instance with 16GB RAM but we are facing a strange issue. Despite any options listed here bitcoind memory usage constantly grows, so ~6min after start it uses 100% of RAM.

Here is the command we use to run bitcoind:
```
usr/local/bin/bitcoind -daemon \
-pid=/run/bitcoind/bitcoind.pid \
-conf=/etc/bitcoin/bitcoin.conf \
-datadir=/data/bitcoind \
-txindex=1 \
-sysperms=true \
-dbcache=5000 \
-maxmempool=100
```
How can we limit bitcoind memory usage? Thanks in advance

Which version of bitcoin core on which OS are you running? (Did you try leaving -dbcache at the default value of 450?)

Hi! We use Bitcoin Core version v0.21.0 As for default dbcache value - yes, we've tried. Now it is running without -dbcache argument (as I understand default value is applied in this case), and it uses ~20GB of memory.
