Unable_to_run_qmail-remote and "trouble in select" problems (are they related)

qmail complains occasionaly he's
"Unable_to_run_qmail-remote./" in the logs, I've
failed to find decent documentation on the web for
such a failure, peeking at qmail's source reveals that
it reports such an error is reported if
read(probablly-qmail-remote-pipe,...) returns zero and
(status_of_qmail-remote-child >> Cool

is 111 [I've no
idea why the byte operation is needed]]. I couldn't
find anything about common errors that causes this
(qmail-log don't have anything about unable to run...)
unable to run, any ideas? Attached a qmail mail
message regarding the Unable_to_run_qmail-remote.
This problem occurs when ezmlm sends mail to all
mailing list members, some recieves that correctly and
for some I recieve the error message email attached.
It also reports "warning: trouble in select", the
manual reports in great details "Bug in the OS", the
source says it reports that when sys/select returns a
certain error value. Also I've googled a bit and found
no reports of this problem. I suspect both problems
are somehow related.
I'm using the latest version of qmail (1.03).
Any ideas? Things to check?

Messages to you from the parshapoints mailing list
seem to
have been bouncing. I've attached a copy of the first
bounce
message I received.

If this message bounces too, I will send you a probe.
If the probe bounces,
I will remove your address from the parshapoints
mailing list,
without further notice.

I've kept a list of which messages from the
parshapoints mailing list have
bounced from your address.

Copies of these messages may be in the archive.

To retrieve a set of messages 123-145 (a maximum of
100 per request),
send an empty message to:
<<usename>-get.123_145@<host A>>

To receive a subject and author list for the last 100
or so messages,
send an empty message to:
<<user name>-index@<host A>>

Here are the message numbers:

Hi. This is the qmail-send program at <some host B>.
I'm afraid I wasn't able to deliver your message to
the following addresses.
This is a permanent error; I've given up. Sorry it
didn't work out.
