Time out on form post

CockpitCMS: 0.9.3
MongoDB: 4.0.10

When posting form values to cockpitCMS the first call works fine, second call sometimes and after the first two calls I get timeouts.

Curl requests made in Postman but olso on PHP, exact the same issue.

curl --location --request POST ‘https://www../api/forms/submit/contactForm?token=*******************************’
–header ‘Content-Type: application/json’
–data-raw ‘{
“form”: {
“field1”: “value1b”,
“field2”: “value2a”

After an hour the first two post work fine again and after these first two I get timeouts again. The post values come true at random even when timeouts ware given.

Is there anyone who can give me direction.
