Hi, Old code(in esx_vi.c) is as below: curl_easy_setopt(curl->handle, CURLOPT_USERAGENT, "libvirt-esx"); curl_easy_setopt(curl->handle, CURLOPT_HEADER, 0); New code: curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1); curl_easy_setopt(curl->handle, CURLOPT_USERAGENT, "libvirt-esx"); curl_easy_setopt(curl->handle, CURLOPT_HEADER, 0); B.R.

Fix code: esxVI_CURL_Connect() in esx_vi.c: I add a new line as following: curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1);
Where exactly in the function ? Can you send a diff of your change ? Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
