I had 2 crashes during a day with a git state from 2026-03-19-022634. 
I've seen the stack trace in the ZFS ARC code and fstat messages about 
"znode_t size mismatch" in fstat in the crash analysis. Normal use case 
of the system, no buildworld running during this time. Since then there 
was an update of the ZFS code and I updated to a git state from 
2026-03-20-131226. I'm testing if this fixes the issue.

Bye,
Alexander.
