mmap() failed: Cannot allocate memory

[sdetweil]

@Egnos said in mmap() failed: Cannot allocate memory:

Mem: 924 495 54 251 374 127
Swap: 99 99

u always have memory available, and never consume any swap space…

pi@MagicMirror:~ $ free -m
              total        used        free      shared  buff/cache   available
Mem:            924         495          54         251         374         127
Swap:            99          99           0

I see that all swap memory is finished … “Used =99 and free=0”.
I dont understand why it is already using swap memory if it is not out of RAM yet …

Why the swap memory always occupied?
Finished the task shouldn’t it free itself?

@Egnos try this

for file in /proc/*/status ; do awk '/VmSwap|Name/{printf $2 " " $3}END{ print ""}' $file; done | sort -k 2 -n -r | less

should give a list of processes using swap, most to least

[sdetweil]

@Egnos so, I would make the swap bigger just for for testing 1 gig

[sdetweil]

@Egnos try this

pm2 stop all
export NODE_OPTIONS=--max_old_space_size=4096
npm start

u can add that export line to the installers/mm.sh
if using pm2
