Release Asuswrt-Merlin 386.9 is now available for AC models

[heysoundude]

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.

cat /proc/$(pidof networkmap)/status | grep ^Vm

So, I hit up ChatGPT:

#!/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:

#!/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
fi

jffs2reset is used in OpenWrt, but not Asuswrt.

Running smooth on my AC86U, past 50 days uptime. The network MAP UI locks up after 20 days though.

I'll take that back to the smartypants. Thanks.

Just as useless.

 

[heysoundude]

it didn't like that.
