Hi Daniel, Is this problem fixed in the latest version? What about the question 2 which related to openssl callbacks in multi-thread? B.R. Benjamin Wang -----Original Message----- From: Daniel P.

Currently curl_easy_init method is called from esxVI_CURL_Connect > method in esx_vi.c. And curl_global_init method is called by curl_easy_init. If we move Curl_global_init to virInitialize, shall we still need to call curl_easy_init from esxVI_CURL_Connect? Did the latest version fix this problem? That is actually the problem. The CURL docs explicitly tell you that it is *not* safe to rely on curl_easy_init in a multithreaded program. You must call curl_global_init explicitly.
