I think understand in which case it happens.

When I receive a REGISTER, I create a transaction since I need to use the t_continue feature to wake up a suspended transaction. However, the save() command of the REGISTRAR module doesn't seem to call t_reply for replying the 200 (it looks like the SL module is used instead). Therefore, I get the warning every time it happens since the transaction is not released explicitly.

Should I call t_release just before exiting the block handling the REGISTER?

Hi,

In my logs, I get a lot of the following warnings:

WARNING: tm [t_lookup.c:1476]: t_unref(): WARNING: script writer didn't release transaction

I force transaction creation from my script to absorb retransmissions as soon as possible. I understand that I need to explicitly call t_release in order to avoid this warning.

What is the most appropriate place in the script to call t_release?

Thanks,

Mickael
