Fork failed: Cannot allocate memory

Hi,

I’m encountering a new issue today without any apparent reason.

Starting today, I began seeing the following error in the logs:

asterisk.c: Fork failed: Cannot allocate memory

After investigating, I found that this issue is related to a dependency. It only occurs when Asterisk attempts to execute external code, such as…

like

or

Does anyone know what could be causing this?

I recently ran into a similar issue with this, with a pretty elaborate call flow, It was on a VM and adding RAM fixed the issue.
