SIGTERM `__CFRunLoopServiceMachPort` #151

Closed msrutek-paylocity closed 2 weeks ago

msrutek-paylocity commented 4 months ago

Platform + Version

iOS 17.5.1 iPhone 15 Pro Max

SDK Version

3.2.2

Framework

Native, SwiftUI

Describe the bug

Hello, since Firebase added support for catching SIGTERM, we started getting thousands of reports of "SIGTERM __CFRunLoopServiceMachPort".

After examining hundreds of SIGTERM occurrences, many indications point to Pendo. We would like to confirm or deny this theory.

We have code inside

func applicationDidEnterBackground(_ application: UIApplication)

that calls the following Pendo method

- (void)track:(NSString *_Nonnull)event properties:(NSDictionary *_Nullable)properties;

Is there anything long-running that might cause the system to perform SIGTERM?

Thanks!

To Reproduce

Yet unknown.

Expected behavior

No SIGTERM.

Hi @msrutek-paylocity , From the crash log, I don't see Pendo involved. Why do you think it's related to Pendo?

msrutek-paylocity commented 4 months ago

I'm sorry, that was probably unrelated, however this crash log mentions Pendo.

The question remains the same - Is there anything long-running that might cause the system to perform SIGTERM?

Hi @msrutek-paylocity Do you know in which scenario this is happening? You mentioned you are calling trackEvent (Pendo API) when app is entering background but in the stack trace we can see that app has entered foreground. Are you calling trackEvent Pendo API in case of entering foreground also?

Hi @msrutek-paylocity! We've made significant memory management improvements in version 3.4.3 that should help with crashes like this. Please upgrade to 3.4.3 and if you notice similar issues, please open a new ticket with the crash logs. Closing this one.
