Linux Exile Server crashing ( SEQ FAULT ) 0x08264f69

Question

Hi there, 

i do have a Linux server running:
 

Quote

 

Debian Sid

Kernel Version 4.3.0-1-amd64

libc6:i386 in version 2.21-6

extDB2.so in version 70

 

it seems that a single player is causing a seq fault in the server process ( arma3server ) 

i looked at the core dump but didnt see anything ... strange

Its always the same Address. so i did a strace while the server crashed:

+++ killed by SIGSEGV (core dumped) +++
 

the client RPT log which is causing this ( tested by having only him playing on the server and crashing it )

it seems for me like a memory leak, monitored the server, via top -p PID and you can see how the memory is getting less and less till crash
