Something crashes your server. Do what this post says: http://forum.sa-mp.com/showpost.php?...32&postcount=7 and compile your PLRP.pwn again with the debug mode. If it gets crashed, show us again what it prints. In cases it shows some information about it.

PS: Update your crashdetect too, look at the last posts, there's 4.12 beta and 4.11.2 versions.
