Hi,
Adding one more point to the above mail, in the function sftp_packet_read in sftp.c file, is it a defect to not to address the zero return from _libssh2_channel_read function in the while loop found in sftp.c:377 ?
Thanks & Regards,Ismail Aseen

Hi,
I have an application which uses libssh2 to transfer files using SFTP. It was working well till I had this problem where libssh2_sftp_init() hangs and does not return while consuming 100% CPU. I did a stack trace using gstack and got the following stack. Please note that this incident occurred only once for me and it is not re created again. This incident happened while communicating with Windows based SFTP server(Tectia). I am using libssh2-1.6.0. version. Is this a known issue? could anybody assist on this?
