KB00019: Python segmentation fault on Ubuntu 22.04

EVA ICS versions: 3.x and above


EVA ICS processes crash with “segmentation fault message” on Ubuntu 22.04 with the system Python.


Ubuntu 22.04 built-in Python 3.10 has got memory leaks which may lead to unpredicted behavior. Consider installing an alternative Python package.

add-apt-repository ppa:deadsnakes/ppa
apt update
apt install python3.8 python3.8-dev

Edit EVA ICS venv:

eva edit venv
# or if even eva-shell is unable to start
AUTO_PREFIX=1 ./sbin/eva-registry-cli edit config/venv

Make sure “system-site-packages” and use_system_pip both are set to false. Set python field to python3.8.

Rebuild EVA ICS venv:

rm -rf /opt/eva/venv

Restart EVA ICS:

eva server restart
