Signal handling?

[mimmus]

Hi,
I read that the project is semi-abandoned but I ask anyway!
We use Tiller to compose "properties" files for our K8s applications. We noticed that often our pods are stuck in Terminating state, they doen't die.
I read in teh docs that:

Signal handling

Not a "gotcha" as such, but worth noting. Since version 0.4.0, Tiller catches the INT,TERM, HUP, QUIT, USR1, USR2, and WINCH signals and passes them on to the child process spawned through exec. This makes sure that if Tiller is killed or signalled then the child process should also cleanly exit or process the signals.

thus it's not a problem with Tiller but probably our Java apps don't manage SIGTERM signals fastly and cleanly.
In your opinion, how can I indagate furtherly?

Thanks in advance
