[Ace-users] Why send() cause a SIGPIPE rather than returning -1 with ECONNRESET

My problem occurs in linux socket API. I am not sure whether it occurs
In linux, I have codes below:
int n = send(sockfd, buf, 1024*1024, 0); //the first send()
n = send(sockfd, buf, 1024, 0); //the second send()
The first send() should block for a while. If client receives an RST
from server when send() is blocking, the first send() returns a
number less than 1024*1024. However, sometimes the second send() will
cause a SIGPIPE signal or sometimes it return -1 with a ECONNRESET
error rather than SIGPIPE.
Why? Any help are appreciated.
