Map server crashed -- related to @Channels

Hey guys me again!

We've solved the issue we had with our player count - however recently another issue has been arising with @channels.

Here's the log:

This is the 2nd time it's happened in two days. Player counts were both above 1600 at time and I also found this: [url="https://rathena.org/board/tracker/issue-9031-map-server-crash/"]https://rathena.org/board/tracker/issue-9031-map-server-crash/[/url] when looking around. We're disabling the command from players for now. Yesterday when it crashed the log we received was:

[url="http://pastebin.com/KZSGNxqi"]http://pastebin.com/KZSGNxqi[/url]

So they're pretty similar.

Any thoughts would be much appreciated.

Cheers

Edit:

We've applied a hotfix to it, testing it out now. Will update later.
