ios - Running leaks on iOS app throws "Cannot allocate mmap" error

Question

I have created an iOS app and need to check the leaks in the app programmatically. (Hence not using instruments directly)

For the above I use the leaks command as follows:

MallocStackLogging=1 leaks -nocontext

At one point of time this was working properly without issues. But recently I have started getting errors and the leaks commands gives different number of leaks each time.

Has anyone faced a similar issue?
