Pexip app crash during long duration calls or multiple short duration calls

Sreekanth1m commented 1 year ago

Describe the bug

Pexip app crash during long duration calls or multiple short duration calls. Issue Description: Pexip app crashes / closes during long hours or multiple short duration calls. Issue: Only Video call and no screen sharing OS: Android 12 H/w: NXP i.MX 8M Plus lowmem.txt

We did test other video platform calls like zoom on same device and don’t observe similar issues.

Attached are the app and tombstone logs.

To reproduce

Make multiple video long duration calls with out re-booting the device.

Expected behavior

Pexip app should not crash.

Version

0.12.0

Additional context

No response

Thanks for the log, it looks very interesting - the first call takes about 1.5 hours, but subsequent calls do not exceed 2 minute duration:

oom_score_adj 0 indicates that the app is in foreground and should have a extremely low probability of getting killed by lmk.

App memory usage at the time of death seems fairly reasonable (around 130 Mb for the first call, even lower for other calls). Profiling may help rule out memory leak, but just from the memory usage I'd say it's not happening in the app itself.

My guess is that there may be some underlying OS issue at play here (leaky codecs?) because the OS appears to struggle allocating enough RAM for the app.

Are you able to provide the following info for further investigation:

Hardware specs of the device
adb shell free output
Memory profiling of the app
A list of codecs present on the device, with their names, supported formats and whether they're hardware or not

Additionally, what commit did you checkout to test this? The issue description lists 0.12.0 (released at the end of May), but the logs indicate that they were recorded earlier (Apr 20). It'd be great if you could run these tests against the latest available commit.

Thanks for the response, while we work on the suggested analysis, please let us know if Pexip Android SDK has a call back when a participant leaves the conference. How the Android app knows about participant events like a new participant joined, left etc.

It's currently not available. I suggest that you open a feature request for discussion/tracking.
