Description

Hello,
I'm using SuperMicro A1SAi-C2750 as small server with jails that was running fine with latest DragonFly BSD 4.8.1,
but since I upgraded to DragonFly BSD 5.0, I'm experiencing random crashes - always in syncache_add.

Tried also clean install and kernel rebuild,
server is actually running DragonFly v5.0.0.6.g0978b-RELEASE

24 hours of memtest is no problem for this server.
Crash summaries of latest server crashes are attached to this issue. I cannot find a patter how to reliably crash that server,
but core.txt.5 was right after reboot-after-panic while trying to copy core.txt.4 per scp from server.

Any help or hint how to fix or debug this problem is appreciated.

Also - should I be worried to see messages like this:
softdep_sync_metadata_bp(1): caught buf 0xffffff80af383f50 going away
on console?

Thanks in advance.
