Linux: X-Plane 12 “Out of memory” error

Users of X-Plane 12 up to (and including) 12.3.0 with Linux distributions other than Ubuntu LTS may experience “Out of memory” errors from network operations (e.g. during Login, weather downloads etc.). This manifests itself in the Log.txt with errors similar to these:

0:00:03.751 E/NET: Download failed with error: 27 for URL https://*******
0:00:03.751 E/HTTP: Error: Out of memory (for URL https://******
0:00:03.751 E/HTTP: Curl Error Buffer: SSL: couldn't create a context: error:00000000:lib(0)::reason(0

The error is caused by incompatibility of OpenSSL configuration in the system with the libraries shipped with X-Plane. This problem will be rectified with X-Plane 12.3.1; until the new version becomes available, you may work around it by running X-Plane with OPENSSL_CONF environment variable set to “/dev/null”, for example:

OPENSSL_CONF=/dev/null ./X-Plane-x86-x64
