CCIf the system detects that a Worker is deadlocked on open connections — for example, if the Worker has pending connection attempts but has no in-progress reads or writes on the connections that it already has open — then the least-recently-used open connection will be canceled to unblock the Worker.https://developers.cloudflare.com/workers/platform/limits/#simultaneous-open-connections
If the Worker later attempts to use a canceled connection, an exception will be thrown. These exceptions should rarely occur in practice, though, since it is uncommon for a Worker to open a connection that it does not have an immediate use for.

scheluded in my test I did this:ScheduledEvent but I didn't find anyway to mock those. The only related mocking function seems to be createScheduledController but it's type is ScheduledController which is similiar but not the same.OOScheduledController or ScheduledEvent typing in the scheduled event and by following this stackoverflow answer on testing the logging: https://stackoverflow.com/questions/76042978/in-vitest-how-do-i-assert-that-a-console-log-happened

As of this release, we impose a limit on the number of outgoing HTTP requests that a worker can make simultaneously. For each incoming request, a worker can make up to 6 concurrent outgoing fetch() requests.await Promise.all(jobs.map(async (job_url) => await $fetch(job_url))*domain.com/*scheludedScheduledEventScheduledEventcreateScheduledController ScheduledControllerScheduledControllerexport const sleep = (ms: number): Promise<void> => {
