https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #13 from Konstantin Belousov --- (In reply to Olef from comment #12) Yes increasing kern.ipc.semusz would also help, but you need to carefully calculate how large to set it. For instance, it is arch-dependent. -- You are rece

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #12 from Olef --- Hi, So, in 12.2 RC2 I indeed still got the kernel panics after initial upgrade. After patching the kernel I've not received this anymore in the last 3 days so all seems to work fine. Thanks for your help! PS

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #11 from Konstantin Belousov --- (In reply to Olef from comment #10) The issue that patch fixes is in HEAD, stable/12, and all 12.x releases. But since it is memory corruption, specific manifestation of it can be arbitrary, for

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #9 from Konstantin Belousov --- (In reply to Olef from comment #8) I am quite sure that there is the issue I described in the review, and since it is a memory corruption kind of bug, it is quite specific to the kernel/machine/ l

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #8 from Olef --- Hi, Thanks, though I did not receive the panic this morning after upgrading to 12.2, will check again tomorrow. If this fault still persists I'll patch in your suggestion. I needed to increase SEMUME as some p

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #6 from Olef --- I can reproduce it with relative ease, i'm on 7 vmcore files so far. Updating now to 12.2-RC2 -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #5 from Konstantin Belousov --- You can try to do something with e.g. ktrace, but this would be hard because system panics and records are not written. Might be sync NFS mount from other machine help, but I do not expect it. S

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250361 --- Comment #4 from Olef --- Fair enough. Is there a way to find out what the calling process was actually doing to cause this? kgdb only gives me the kernel fault, but doesn't give me anything on the state of the calling process. -- You
