I am not aware of problems with Linux kernels.
I have two pieces of home work for you.
1) Perhaps your system runs "security" software that is not configured
to allow Postfix to send file descriptors over UNIX-domain sockets.
In that case there may be errors in the logfile. that explains
WHY it cannot
2) There is more mail logging from the process 1177 BEFORE it gives
up. Please show the complete record.
