Metadata Broker (aarch64) crash #221

Bug report description

consume_analytics_metadata crashing on aarch64 (P3265-LV FW 11.9.60)

To reproduce

I have been testing the Metadata Broker for few days and developed my own ACAP based on your example to find out my app was crashing after few hours of running. I have then decided to run the example app to find out it was crashing as well. The issue seems to be related somehow to the syslog. Commenting out

syslog(LOG_INFO, "metadata received from topic: %s on source: %s: Monotonic time - " "%lld.%.9ld. Data - %.s", channel_identifier->topic, channel_identifier->source, (long long)timestamp->tv_sec, timestamp->tv_nsec, (int)payload->size, (char)payload->data);

results in the app never crashing.

I have then decided to build a test acap flooding the camera with syslogs. The metadata broker example is the one that crashes while other acaps are not affected by it.

The same example 'consume_analytics_metadata' works just fine on armv7hf arch (tested on Q1615 MKIII fw 11.9.60)

The scene I am testing is a high traffic highway (see attached short video)

Steps to reproduce the behavior:

  1. Install the 'consume_analytics_metadata_1_0_0' acap on ARTPEC8 camera (I tested on P3265-LV) FW 11.9.60
  2. Make sure the camera views faces lots of traffic (the more, the quicker the issue will happen)
  3. Check after few hours of running that the app stopped.

Environment

Additional context

As mentioned above the issue can be avoided by commenting out the syslog, so this issue doesn't have a big impact on my current dev. but definitely worth investigating in my opinion.

Hi @paromarc,

Sorry for the wait, but we are not able to recreate your bug. We have run the ACAP on a P3265-V with version 11.9.60, looking at a busy scene in over a week without it failing.

Can you still recreate the bug? If yes, have you made any modifications to the ACAP or had something else running on the camera?

Hey @kevin-barudde-work , thanks for testing on your end ! I defaulted my P3265-LV and I cannot duplicate on my end either. Maybe something weird happening on my camera. I mess with it a lot, so I am not surprised :-) I think we can close this for now :-) Thanks again for checking on your end !
