Hi!
We asre using a ldirectord configuration that uses an external-perl to check
for connections. That worked in SLES11SP3, but I just discovered that IPVS
thinks all real services are up, when in fact the perl module reports they are
down.
Could this be due to some bad change?
Trying to debug, I only found this:

??? This server should be UP!
[...]
The line in question is in _service_up() at "if ($r->{failcount} > 0) {".
As a quick work-around I changed "checktype = external-perl" to "checktype =
external", and it works as before now.
