On FreeBSD, "cd /usr/share/man/man2" followed by "zgrep ECONNABORTED *"
shows that aside from intro(2) and errno(2), there's only one page, so
only one system call explicitly documented as returning this.
accept(2):
[ECONNABORTED] A connection arrived, but it was closed while waiting
on the listen queue.
It sounds as though your system is a bit overloaded and not accepting
connections fast enough. Does "netstat -aSL" show many connections in
the listen queue?
Anything especially funky in your setup to cause delays?
