[rsyslog] High cpu usage - rsyslog 5.4.0.

[Rainer Gerhards]

Hi,

thanks for the information. I have crafted a big patch package for v4 the
last two weeks. I will try to merge it in to v5 this week (I guess this will
be a bit harder than usual). It may fix the issue.

If you have a moment or two, it would be interesting to know if 5.5.2 has the
same problem.

Rainer
