Hi, This error is repeatable at my LAN. sipp(OS is centos 4.6) --- LAN ---> program using pjsip-ua(OS is windows XP) I use sipp to gen call to program. If I kill sipp using ctrl-c, the program will log this message and udp transport stop working. I don't know detail about winsocket.As I know this isn't fatal error for udp socket at linux, ignore this error and continue use this udp socket is ok. How can I recover this issue? 19:44:53.859 udp00B0F4D8 FATAL: pj_ioqueue_recvfrom() error, UDP transport stopping! Error: [err 130054] Connection reset by peer (WSAECONNRESET) regards, Gang -------------- next part -------------- An HTML attachment was scrubbed...
