crontab

I get this question from the hosting company:
----
there is a curl_exec function occasionally executed. I suppose this is a cronjobs on its base http requests.
I can create a native crontab for you if you can specify when and what should be in the crontab.
----
Sorry for the translation.
I do not know where I can look for this and what it is. Can someone help me to let him know what should be in the crontab?

Thnx

Hi

I'm afraid I will not be able to help. Our template doesn't need a cronjob, so it's not coming from our products. It's probably from some 3rd party extensions, unfortunately I do not have a knowledge about which one could it be. I would advice to block it.
