Вы всё это приравниваете по серьезности к сломавшемуся log-демону?
Ко всему этому ещё прибавляются прелести в виде:
Pipe Capacity
A pipe has a limited capacity. If the pipe is full, then a write(2)
will block or fail, depending on whether the O_NONBLOCK flag is set
(see below). Different implementations have different limits for the
pipe capacity. Applications should not rely on a particular capacity:
an application should be designed so that a reading process consumes
data as soon as it is available, so that a writing process does not
remain blocked.
PIPE_BUF
POSIX.1-2001 says that write(2)s of less than PIPE_BUF bytes must be
atomic: the output data is written to the pipe as a contiguous
sequence. Writes of more than PIPE_BUF bytes may be nonatomic: the
kernel may interleave the data with data written by other processes.
POSIX.1-2001 requires PIPE_BUF to be at least 512 bytes.
