When a broker is ungracefully shutdown on windows, it won't restart, and shows the following message: [2017-10-10 14:41:20,196] INFO Loading logs.

When replacing these two lines with the following, recovery continues and everything seems to be working well: if(timeIndexFileExists) timeIndexFile.delete() indexFile.delete() Kind regards, Niels Hoogeveen -- This message was sent by Atlassian JIRA (v6.4.14#64029)
