samp-plugin-crashdetect Server crashed due to an unknown error

Hello, I'm using crash detect with the latest version.

I'm using CentOS 7 as OS for hosting SAMP server. All the plugins are listed at the end of the log. All the plugins are up-to-date.

Script is compiled with -d3 argument. We had

trace pfn crashdetect cs.txt

in our server.cfg file and after deleting latest two functions before crash, server continues to crash.

So what's the bug? or you're looking for help with your crash?

@Zeex Is there a way for crashdetect to dispaly more of a usefull informations (ex. call stack or something else) when server goes unexpectedly offline.

Also, if you have any additional information regarding to this crash? What should we look for?

We have -Z+ , -d3, all plugins up-to-date. We're using CentOS7.

It does display a call stack when possible, but when it says "due to an unknown error" it usually means that the AMX call stack was empty at that time. Looking at the output, it seems that the crash happened in some worker thread in samp03svr. I'm not much familiar with the SA-MP server architecture, as far as I remember it does networking in a separate thread, so this could be it.
