Public bug reported:
Binary package hint: keepalived
When using keepalived last version from Dapper, when it has a genhash
failure on http service check it keeps writing every second to logs
filling the hard drive, using 100% CPU and the checker get "zombie". A
restart of the process does not work on it, and if it happens on the
master server, it also starts on the slave server, making the service
unavailable in 90% of the requests. I installed by hand compiling 1.1.15
and problem goes away for now, with 1.1.14 the issue still happens.
