Issue with running nanomq 0.20.5 on 32bit armv7a architecture

[destroyer5656]

Describe the bug
Seeing issues with nanomq starting as a zombie process when built for this architecture, seems to work on 64bit arm environments but not for 32bit arm environment.

Expected behavior

nanomq should start up not as a zombie process, and should be killable.

Actual Behavior

nanomq never starts up successfully

To Reproduce

If possible include actual reproduction test code here.
Minimal C test cases are perferred.

Environment Details

• NanoMQ version
• 0.20.5
• Operating system and version
• Linux imx6ull 5.4.70-2.3.0 1 PREEMPT Fri Aug 11 07:46:10 UTC 2023 armv7l armv7l armv7l GNU/Linux
• Compiler and language used

nanomq old_config file has:
websocket.enable = false
enable_ipc_internal = false

compiler:
armv7a_gcc_6_5_0

binary:
/usr/bin/nanomq: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=8563969b188aac30e2eed2df45bbf3bb2cfdbbfc, stripped

testing scenario
Using on a armv7a embedded device, we also have a aarch64 device that compiles successfully and runs properly on the new release.

Client SDK
We are using AWS IOT core on the other side.

If possible include the mqtt sdk you used to connect to nanomq
Minimal C test cases are perferred.

[JaylinYu]

Could you verify if this issue only happens on 0.20.5? does 0.19.5 works fine?

[destroyer5656]

Yeah correct 0.19.5 and 0.20.0 works fine, atleast for a while until the memory leak crashes the program.

[JaylinYu]

Thats strange. No memleak detected with ASAN on my dev env. Noted that session keeping and msg caching might result in the wrong report of memleak. Could you submit your memleak info?

And this issue is a mistake of mine, due to this pr nanomq/NanoNNG@ded86c0

Will re-release 0.20.5 today!

[JaylinYu]

I have pushed a fix. Could you have a try on the master branch?

[destroyer5656]

Awesome thanks!

[JaylinYu]

Awesome thanks!

I suppose the fix works? Will proceed to modify the release.

[destroyer5656]

Testing the fix right now.

For the memleak info, its hard to reproduce as it only occurs after 2+ days of load testing the broker with a high message amount. In 0.19.5 it was crashing more often but in 0.20.0 it was only occurring after 2 days of runtime at a really high message rate. When running normally with a standard message amount we don't notice the issue, and its hard to get debug logs as the rest of the system starts crashing.

Ok, perhaps AWS IoT bridging is the one to be blame. Heavy test conducted on nanomq, but AWS Bridge is not include, due to lack of resources. Happy to fix it if you got more log. (set nanomq log to "info" is enough)

And... what do you mean by "rest of the system starts crashing" ? Seems like an OS issue

[destroyer5656]

The rest of the system runs out of ram and oom reaper starts killing all the running processes.

[JaylinYu]

The rest of the system runs out of ram and oom reaper starts killing all the running processes.

Understood. Limit the queue length (max_mqueue_len) and the num of ctx (parallel) could help on reducing the memory ceiling of nanomq:

mqtt = {
  max_packet_size = 1KB       # Maximum packet size NanoMQ can accept and send, 1B~260MB.
  max_mqueue_len = 2048       # Maximum length of the in-flight window queue
  retry_interval = 10s        # Retry interval for QoS 1/2 message delivering
  keepalive_multiplier = 1.25 # Multiplier for MQTT keepalive timeout. 
  property_size = 32          # Maximum size for a MQTT user property.
}

[destroyer5656]

Will try that thanks! Will open a new issue once I get some debug logs from the aws iot bridge! Also confirming it no longer segfaults when running on latest master on our 32bit armv7 platform. Thanks for the quick help.

[destroyer5656]

I tried tuning the memory but nomatter what I do I can't get it to reduce below 150 megabytes after a certain amount of runtime it just starts increasing albeit very slowly.
here is my current config:

cat /nanomq_config.conf
websocket.enable = false
enable_ipc_internal = false
max_packet_size = 10240
msq_len = 1024
keepalive_backoff = 1250
property_size = 32
parallel = 2

[JaylinYu]

Hi, I was saying queue length (max_mqueue_len) and the num of ctx (parallel) help limit the memory usage. However, I cannot calculate a precise number of memory consumption. It is also affected by the size of msg and number of connected clients.
While the number of clients and pressure remain unchanged. By reducing the msq_len and parallel, you should be able to get a lower footprint comparatively.

As for your parameters, you could try to reduce the number of msq_len to 256. but it only works if you see logs like "Warning: msg lost due to reach the limit of lmq". (cache msg occupies memory)

Otherwise, perhaps the memory is used by sockets and aios, pipes for sustaining MQTT connections.
