Hey everyone,
I’m running into an issue with a function that triggers a post-process containing a sleep() (up to 45 min total) and then sends auto-reply emails. This runs multiple times a day, potentially with 100+ simultaneous inputs.
The strange part: some post-processes complete fine, but others stop silently mid-execution — no errors, no logs, no continuation. The executing flag remains true, and we have no clue where/why it stopped.
When running manually, everything works fine
Error handling is in place, no errors thrown
Post-process is the only place we use
sleep()and do long waiting
Is there:
A concurrency limit for post-processes?
A memory or timeout limit even if not documented?
Any guidance for debugging this kind of silent exit?
Would love help from anyone who’s hit similar issues — or insight from the Xano team if this behavior is expected under load.
Thanks in advance!
