    {panel:title=Moderator Note|borderStyle=dashed|borderColor=#ccc|titleBGColor=#F7D6C1|bgColor=#FFFFCE} This issue is most commonly caused by a broken installation of *Avast!* free edition Anti-virus software. A reinstallation of Avast! and a reboot usually fixes it. *McAfee* anti-virus software (and derivatives) are also know to cause this issue, and currently the only known solution is to uninstall this software to correct the problem. Also *Outpost security* may cause that issue. {color:red} Please visit the [#minecrafthelp channel|http://webchat.esper.net/?channels=minecrafthelp] for further support. {color} {panel} ---- This is an automatically generated report based from the following crash: http://hopper.minecraft.net/crashes/minecraft/MCX-294053/ Crash: {code} java.lang.IllegalStateException: failed to create a child event loop at io.netty.util.concurrent.MultithreadEventExecutorGroup.<init>(MultithreadEventExecutorGroup.java:61) at io.netty.channel.MultithreadEventLoopGroup.<init>(MultithreadEventLoopGroup.java:49) at io.netty.channel.nio.NioEventLoopGroup.<init>(NioEventLoopGroup.java:61) at io.netty.channel.nio.NioEventLoopGroup.<init>(NioEventLoopGroup.java:52) at mo.<init>(SourceFile:36) at net.minecraft.server.MinecraftServer.<init>(SourceFile:114) at brh.<init>(SourceFile:38) at ays.a(SourceFile:1585) at bbs.e(SourceFile:162) at bbt.a(SourceFile:214) at bam.a(SourceFile:186) at bbs.a(SourceFile:187) {code} The following is the first clean report made public about this crash: {code} ---- Minecraft Crash Report ---- // Don't do that.
