Hi,
I have a problem with an kafka installation and need some help to go ahead with my issue. Maybe someone can help. If I start kafka, the process is being killed during the startup phrase after some seconds: [2020-04-20 17:12:26,244] INFO [ThrottledChannelReaper-Fetch]: Starting (kafka.server.ClientQuotaManager$ThrottledChannelReaper) [2020-04-20 17:12:26,248] INFO [ThrottledChannelReaper-Produce]: Starting (kafka.server.ClientQuotaManager$ThrottledChannelReaper) [2020-04-20 17:12:26,255] INFO [ThrottledChannelReaper-Request]: Starting (kafka.server.ClientQuotaManager$ThrottledChannelReaper) [2020-04-20 17:12:26,350] INFO Loading logs.
