Gateway reports memory allocation error

[moubctez]

There is a problem with "release" build. Rust optimises some memory access, and the process may crash.

Hello @moubctez

Could this issue be related to this error in OPNSense ?

Failed to retrieve WireGuard interface statistics: BSD error: Memory allocation error

We notice this error every minutes:

We also noticed that we do not see the connected clients in the Core (VPN Overview), we suppose that this may be related?

Thanks,

@maxime-morel Yes. This will be fixed in the next release. Stay tuned.

Gateway 2.0.3 has been released which fixes the problem.
