Hi to all. The first OmniOS server I put in production is rebooting from time to time... I suspect that the cause lies in ipfilter, which I have enabled and configured, but I'm not able to track the issue to the root cause.

Here is the fmdump output and a basic analysis of the core dump file: paste.omnios.org/?eb3d39a5705b95cf#…2LgPPKsa5BJqCVMELdmj1UJ46Y1JVwftz6N

I'd be very grateful if someone more skilled than me can suggest how to further analyze the issue. Thanks! :)

warden: running `::status` in mdb would be helpful

It appears to be a problem with grabbing a mutex, but I see nothing obvious in fr_tcp_age(). Makes me wodner if a stack frame is missing because it does call fr_movequeue(), which does try to enter a mutex.

Also, wow, didn't know we had some K&R C still floating around.

Thank you rzezeski, here it is the ::status output: paste.omnios.org/?d6088f55f52d9cb7#…hu91NQpiRgRkTCzXWRqsTdhZ8qKWvMJcAcS

please note that all these debug commands are arcane for me... threat me like a baby! :)

Okay, so a null pointer. Let's look at the tqe argument passed to fr_movequeue(). Run this in mdb: `fffffe599ee636a0::print -t ipftqent_t`

It also might be nice to just keep adding to the same paste if that's possible so everything is in one spot.

Thanks. PrivateBin seems not to allow me to modify existing paste, so I merged all text here: box.messagecloud.it/index.php/s/2Ag…zmi6M8/download/OmniOS_coredump.txt

Okay, now let's look at the tqe_ifq member. Run this in mdb: `fffffe599ee636a0::print -t ipftqent_t tqe_ifq |::print -t ipftq_t`

great, I've just updated the text file (also readable inside the browser window at this URL: box.messagecloud.it/index.php/s/2Agx3n367zmi6M8 )

warden: weird, it seems a NULL pointer was passed to mutex_enter(), but the code (albeit very confusing) doesn't seem like it should do that. So I might be making the wrong assumption. We are missing a stack frame because mutex_enter is optimized and doesn't store one. We should be able to look at it by doing something like: `fffffe007d7fcbd0,30/nap`

rzezeski: I barely understand what you mean, but I've just updated the text file with the last output. Thanks!
