Problem Description:

1122704: socket library accept() may leak file descriptors
1127186: accept() can leak incoming connections - server stop accepting connections

Ftp/rlogin/telnet or some other service provided by inetd might stop working
(e.g. by allowing no more rlogin's.)
If these messages show up in /var/adm/messages you are seeing this bug:
        inetd[120]: accept: Protocol error
        inetd[120]: accept: Too many open files

This patch is being reissued to remove a symbolic link in the
SUNWcsu patch package


(from 100949-03)

rexec does not look for information in the .netrc file.

(From 100949-02)
If the a socket file descriptor is set up for non-blocking I/O then the
send() call will return with errno being ENONMEM instead of the correct
EWOULDBLOCK.

(From 100949-01)
This patch fixes the problem:
getservbyname(3) cannot find the service name in /etc/services file
if the 2nd parameter is NULL or empty string "".
