iOS app runs smooth in manual testing but crashes in Appium 1.9.1 Automation

Appium Version : 1.9.1
iOS Version : 12.0
Xcode Version : 10.0
App compiled using xcode version : 10.1
Framework : Hybrid (Maven+Testng+Apache poi+Java)
Java version : 1.8.1

Applications runs smoothly while testing manually but it starts crashing when running automation with above configuration in some specific screens.

Automation is working fine with appium 1.7.2 and 1.8.0

I dont know what is wrong with Appium version 1.9.1

Xcode device logs shows critical memory error and app crashes.
