If you start more than 3-4 bots, you should increase the shared memory. Otherwise the TS3 client may hang.
The following commands can be used to increase the shared memory immediately: (Remains only until the next restart)
echo "2147483648" > /proc/sys/kernel/shmmax;echo "2147483648" > /proc/sys/kernel/shmall;echo "65536" >/proc/sys/kernel/shmmni
And in the file "/etc/sysctl.conf" add the following lines: (Set at server startup)
kernel.shmmax=2147483648
kernel.shmall=2147483648
kernel.shmmni=65536
Then the bots restart. Done.
