SubjectRe: 2.4.0-ac3 write() to tcp socket returning errno of -3 (ESRCH: "No such process")
   Date: 	Sun, 7 Jan 2001 23:55:28 -0600 (CST)
From: Paul Cassella <pwc@speakeasy.net>

[1.] One line summary of the problem:

write() returns -1 and sets errno non-sensically. 2.4.0{,-ac[23]}

What you describe I can only say is "impossible".

There are only four cases when _ANY_ part of the ipv4 networking stack
can return ESRCH. These four cases are:

1) Adding a route
2) Deleting a route
3) Adding a FIB routing rule
3) Removing a FIB routing rule

None of them can occur via TCP socket writes (only netlink socket
operations or socket control calls).

Therefore I suspect you are perhaps getting rather some form of memory
corruption or similar, really, please search the networking code for
ESRCH value usage, you will see.

Later,
