dch, Back in the day on HP-UX, IBM AIX, Solaris, the ps namespace was global and every user could see all of the process slot information or all processes.

Are Broadcom nics (bge) a sore point for FreeBSD users?

I think bge's generally not bad

broadcom wifi is rougher

Ok. I have an older server, still works well, and the nic's are just ordinary. lose connection, or drop IPv4 for no reason. all 4 of them.

I've tried loading driver on boot using loader.conf, doesnt seem to help any.

i'm so confused. my vmstat says i'm using 500G of ram?

i have 32G ram, 8G swap. i count 5 GB in tmpfs, and 14GB in major app procs. i should be 19GB/32G used, that's over half.

btop says memory is 8% used

Demosthenex: Looks like avm includes all virtual memory used, whether it's got actual pages swapped in or not. So something as simple as malloc(10U * 1024 * 1024 * 1024) will not actually allocate memory immediately, but will take up virtual address space, and look like 10G are used.

Which means the 500G you see is overcommitted, and doesn't reflect reality; unless all programs "cash in" their memory at the same time, the system won't try to actually _use_ that memory.

JSHenry: interesting. i'm just trying to find something that's closer to my manual calculation

was trying to determine how much i had to spare, to bump up the 14G apps

still can't get over btop says 92% free

So, I'm no expert on this at all; but are you sure that 14GB is accurate? At the very least shared libraries are going to make it a bit difficult to gauge exact memory usage, and how much of that 14GB is swapped out/not-yet-written-to?

Just for the sake of illustration, a C program that does this: "mmap(NULL, 100UL * 1024 * 1024 * 1024, PROT_READ | PROT_WRITE, MAP_ANON | MAP_PRIVATE, -1, 0)" looks like it takes up 100GB in top's output. But my VM only has 1GB allocated, so there's no way it's actually _using_ 100GB right now.

JSHenry: its java, so i tell it the max memory usage. -XmX 7G

so, here's an example, though it reads like line noise dpaste.org/hcEv0/raw

the max RSS is 6.3G which sounds right

the other major one is 4.5G RSS. to 9.8G java, 5G tmpfs = roughly 16G used. of 32G ram.

that's still half :P

the tmpfs work area is capped at 16G, 5G used atm

Sorry, no ideas there; I don't know how btop calculates memory usage, so I'm not sure why it would disagree with what you're seeing elsewhere.

dpaste.org/uQW2i/raw that's top

and... despite being fluent in aix and linux, i can't get 50% out of anything there
