Connection cache size

[iamoskvin]

I am using only curly API in my code.
So, I think that for each curly request it creates additional easy_handle and adds it to common multi_handle. So, according to libcurl documentation the total connection cache size should be 4* easy_handle amount.
So, I should not see connection cache size limits. But I am regularly see in the logs "Connection cache is full, closing the oldest one"
https://curl.se/libcurl/c/CURLMOPT_MAXCONNECTS.html

What is my mistake? Why do I meet this?
Thank you.

We do not set any value for that option, so it should fallback to libcurl's default behavior, which is the one you mentioned above. 🤔
