@Rataplan626, the new ZimaBrain CE Docker version is now available. This update adds persistent local memory, system-health history, memory/swap checks, failed-service analysis, SMART/NVMe trends, container history and ZimaOS update comparison.
This should be much more useful for your recurring hard-lock issue because you can create a baseline, then after the next crash and reboot ask the same or reworded questions and ZimaBrain will compare the new evidence with the previous scan.
Please test:
Give me a complete system-health assessment.
What changed since my previous scan?
What changed after my latest ZimaOS update?
Which services are failed or degraded?
Is memory pressure high?
Then export the redacted session. A complete hard lock may still leave no final journal entry, but the new memory layer should help identify changes or worsening signals leading up to repeated crashes.
