For best operation, this thread should run at a higher priority, however the VM was unable to change the priority. The effect is that heavily loaded systems may experience some latency issues. If this occurs, please create the appropriate configuration file in /etc/security/limits.d/ as shown below: cat <<END | sudo tee /etc/security/limits.d/pharo.conf * hard rtprio 2 * soft rtprio 2 END and report to the pharo mailing list whether this improves behaviour. You will need to log out and log back in for the limits to take effect.
