Short: won't work out of the box on RHEL5.1.

Long:
Download of RPM to RHEL5.1, installed libmudflap and libmudflabp-devel,
build and installed rsyslog, did not install the mysql-package.
Felt annoyed when I realised that the package moved /etc/rsyslog.conf
to /etc/rsyslog.conf.rpmnew and copied a new configuration
to /etc/rsyslog.conf. Changed back to my old configuration.

Did "/sbin/rsyslogd -n -o -r514 -m 0". The daemon starts and that's it.
Killed it, did "/opt/rsyslog/sbin/rsyslogd -n -o -r514 -m 0" (the
"original 1.19.10") and it logged fine. So both the command-line and the
config seem to be valid. But the modified rsyslog+mudflap just sits
there in a loop, waiting for something to happen (according to strace).

Last lines indicate some DNS-problem and in fact adding "-x" to the
commandline helps. Now I'm waiting for the next crash to send my
output^.

No crash so far. The load is noticably higher, but still acceptable.
Now I killed the debugging-release and used precisely the same
commandline to start the regular release, which caused some crashes
here.
As I mentioned the debugging-release had some problems with DNS, so I
can't run it the same way I usually try to run rsyslog. So I'm not quite
sure wheter or not the results can actually be compared.
Anyway, I'll try the new command-line with 1.19.10 first, if that
crashes I'll switch to 1.19.11.

Patrick,

excellent, many thanks. We stay tuned for updates. I am very hopeful for
the compiler switch issue...

Hi all,

just a small update: 1.19.10-debug worked for two days without problems.
1.19.10 crashed after 5 hours.
Now I'll give 1.19.11 a try....

Patrick,

ok - even though this sounds somewhat silly, I think this is good news.
It is evidence that the problem is not related to the option. That, too,
points into the direction of a threading issue, so it is consistent with
former findings.

What I now hope is that the rest of the analysis is true, too. In that
case, 1.19.11 should work...

Thanks for all your help. Much appreciated.
Rainer
