[syslog-ng] I/O error occurred while reading; fd='4', error='Operation not permitted (1)'

[Matt Miller]

I seem to have 2.0.0 running in a jail via the "-C" option, but when I
start the service I see the following in
/var/local/chroot/syslogng/var/log/syslog:

Jan  2 16:48:19 xpc1 syslog-ng[19522]: syslog-ng starting up;
version='2.0.0'

Jan  2 16:48:19 xpc1 syslog-ng[19522]: I/O error occurred while reading;
fd='4', error='Operation not permitted (1)'

The daemon does seem to continue to run fine, since I am seeing
facilities logging their activity to
/var/local/chroot/syslogng/var/log/syslog.  However, that second line
above seems to indicate a problem.  When I run syslog-ng without the
"-C" option I don't get this second line.

Am I missing something in my jail?  Is the jailing process documented?
