API call fails to complete in child pipeline

Hello,

I am trying to run a parent-child pipeline using the pipeline execute snap. Lately, I have been getting the error mentioned below in one of the child pipeline instances. The other child pipeline instances complete successfully. This specific child pipeline gets stuck on a SOAP API call snap and fails to execute after a certain point.
I have set the pool_size to 2 and I have attached the pipeline screenshot below for reference. Any help with this would be great,

Thanks,
Amol.

Can one of you help me with this or redirect it to someone who can?
Thanks!

Has anything changed in your environment? Updated any Snaps or Java libraries?

I’m asking our Dev Team, but if it’s something that was working but has stopped, you may need to go through Support.
