Hi syslog-ng people,

I've just installed syslog-ng 1.4.15, using libol 0.2.23 as directed in
the INSTALL instructions.

I am running it on a:

    SunOS 5.7 Generic_106541-11 sun4u sparc SUNW,Ultra-250

When I run syslog-ng with the attached configuration file, it runs for a
short period (< 10 minutes) and exits.  When it exits, I get this
message in one of the output files:

    syslog:io.c:263: failed assertion `i == nfds'

which file it appears in varies, which is presumably down to a file
descriptor mixup.

line 263 of io.c in libol is indeed:

                assert(i == nfds);

When I run syslog-ng in debugging mode (with the -d -v switches), this
problem does not occur (I have run for two days without the fault).  I
assume this is because in debugging mode fds 0,1 & 2 are kept open,
whereas they are closed when syslog-ng becomes a daemon (note many
assumptions :).

I have tried to find reference to this problem on the web without
success - the archives of this list aren't searchable as far as I can
find, so apologies if this is a known and fixed problem.

Many Thanks,

Doug Winter
