Hi, We have enabled mwan3 (version 2.11.4) functionality with OpenWRT version 22.03 and we see that four mwan3rtmon processes are running, two each for IPv4 and IPv6. Whereas with mwan3 (version 2.8.16) that came with OpenWRT version 19.07, has only one process for mwan3rtmon running for both IPv4 and IPv6. This has caused an increased memory usage on OpenWRT version 22.03 by 3 times when compared to OpenWRT version 19.07. This is a huge concern for us as we have limited memory on our router product.
On debugging further, we see that mwan3rtmon script is invoking a child process, the reason behind observing two processes per each IP type. Refer(line number 155) at https://github.com/openwrt/packages/blob/master/net/mwan3/files/usr/sbin/mwan3rtmon Can we know the reason behind creating child processes? To reduce memory usage, if we disable creation of child process, what functionality of mwan3 will be affected? Also, is it recommended to use mwan3 (version 2.8.16) with OpenWRT version 22.03 as this has no child processes and only one mwan3rtmon process for both IPv4 and IPv6? Below is the observation captured from device. //mwan3_2.8.16 root@OpenWrt:/# ps w |grep mwan 22963 root 1672 S {mwan3rtmon} /bin/sh /usr/sbin/mwan3rtmon //mwan3_2.11.4 root@OpenWrt:/# ps w | grep mwan 2071 root 2332 S /bin/sh /usr/sbin/mwan3rtmon ipv4 2072 root 2352 S /bin/sh /usr/sbin/mwan3rtmon ipv6 2169 root 2296 S /bin/sh /usr/sbin/mwan3rtmon ipv6 2176 root 2296 S /bin/sh /usr/sbin/mwan3rtmon ipv4 Thanks, Ravi _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
