I was testing v23.0rc2 compiled.

`./configure --without-miniupnpc --without-natpmp --enable-hardening --without-bdb --with-qrencode --with-zmq --with-sqlite=yes --disable-external-signer`

bitcoin.conf:

> assumevalid=0
> blockfilterindex=1
> coinstatsindex=1
> dbcache=1000
> prune=0
> sandbox=log-and-abort
> txindex=1
> cjdnsreachable=1
> discover=1
> i2psam=127.0.0.1:7656
> listen=1
> listenonion=1
> networkactive=1
> peerblockfilters=1
> proxy=127.0.0.1:9050
> addresstype=bech32m
> avoidpartialspends=1
> changetype=bech32m
> maxapsfee=0.001
> walletrbf=1
> shrinkdebugfile=1

I deleted my data directory (/home/user/.bitcoin) to start a fresh download of the blockchain to test any errors.  Ran out of space, and after deleting more and trying to start bitcoin-qt again:

> ERROR: The syscall "linkat" (syscall number 265) is not allowed by the syscall sandbox in thread "main". Please report.
> terminate called without an active exception
> Aborted

and in debug.log:
