After a very clean upgrade and numerous observations across 10 days, I’d like to report that my RT-AC86U with 386.9 is suffering from the same “memory leak” described in some of the 388.1 threads. Further investigation using top -m indeed confirms that networkmap has been steadily growing at a rate of 2MB every 24 hours. Everything else remains unchanged in terms of memory usage.

I did not notice this behavior with 386.5_2 or 386.7_2. I realize networkmap is closed source and there’s not much @RMerlin can do about this, but I thought I’d share my findings here as a reference.

It would actually be nice to get feedback from other forum members about their networkmap size behavior under 386.9, particularly for the RT-AC86U. Thanks in advance.
I'm also seeing this on my AC86u
Until a power interruption yesterday, however, I had been experiencing a trouble-free 50-ish day uptime otherwise, and fully expected it to continue until upgrading to 386.10

Thanks for your confirmation @heysoundude. And I fully agree - despite the observed memory leak with networkmap, everything works very well from an operational standpoint.

So far, I see networkmap VmSize increase by 4 kB after every time it spawns asusdiscovery.
Code:
cat /proc/$(pidof networkmap)/status | grep ^Vm
 
So, I hit up ChatGPT:
chatGPT-Merlin.png

Bash:
#!/bin/sh

MAX_JFFS_SIZE=32 # Max size of JFFS partition in MB
MIN_FREE_SPACE=5 # Min free space on JFFS partition in MB

while true; do
  JFFS_SIZE=$(df -m | grep '/jffs' | awk '{print $2}')
  FREE_SPACE=$(df -m | grep '/jffs' | awk '{print $4}')
 
  if [ "$JFFS_SIZE" -gt "$MAX_JFFS_SIZE" ] || [ "$FREE_SPACE" -lt "$MIN_FREE_SPACE" ]; then
    logger "JFFS partition too large or low on free space, cleaning up..."
    jffs2reset -y && reboot
  fi
 
  sleep 3600 # Sleep for 1 hour before checking again
done

where does one stick that if they want to give it a shot?
 
and after seeing @dave14305 's post, I went back to the machina:

Bash:
#!/bin/sh

MAX_JFFS_SIZE=32 # Max size of JFFS partition in MB
MIN_FREE_SPACE=5 # Min free space on JFFS partition in MB

if [ "$1" == "add" ] && [ "$2" == "ASUS" ]; then
  JFFS_SIZE=$(df -m | grep '/jffs' | awk '{print $2}')
  FREE_SPACE=$(df -m | grep '/jffs' | awk '{print $4}')

  if [ "$JFFS_SIZE" -gt "$MAX_JFFS_SIZE" ] || [ "$FREE_SPACE" -lt "$MIN_FREE_SPACE" ]; then
    logger "JFFS partition too large or low on free space, cleaning up..."
    jffs2reset -y && reboot
  fi

jffs2reset is used in OpenWrt, but not Asuswrt.
 
Bash:
#!/bin/sh

MAX_JFFS_SIZE=32 # Max size of JFFS partition in MB
MIN_FREE_SPACE=5 # Min free space on JFFS partition in MB

if [ "$1" == "add" ] && [ "$2" == "ASUS" ]; then
  JFFS_SIZE=$(df -m | grep '/jffs' | awk '{print $2}')
  FREE_SPACE=$(df -m | grep '/jffs' | awk '{print $4}')

  if [ "$JFFS_SIZE" -gt "$MAX_JFFS_SIZE" ] || [ "$FREE_SPACE" -lt "$MIN_FREE_SPACE" ]; then
    logger "JFFS partition too large or low on free space, cleaning up..."
    echo 2 > /proc/sys/vm/drop_caches
  fi
fi

Just as useless.
