Unbound stopps suddenly

[MiRei]

Good Morning,

thanks for the new 26.7!
OPNSense is a truly great product; thank you very much for maintaining and
further developing it.

The upgrade to 26.7 went smoothly. After two days of use, I've now noticed
Unbound crashing for the second time, with the following error message:

 (unbound), jid 0, uid 59, was killed: failed to reclaim memory

After that, I can manually restart Unbound, and the system continues to run normally.

Any ideas?

Thanks a lot!
