Hydra: I can't use all of my runtimes

This is an issue with the default setup of Linux which restricts the number of runtimes that can be used at any one time. To fix this, you need to log in as root and edit the /etc/xinetd.conf file.

Here is the example of the few top lines of the xinetd.conf file:

# # xinetd.conf # # Copyright (c) 1998-2001 SuSE GmbH Nuernberg, Germany. 
 # Copyright (c) 2002 SuSE Linux AG, Nuernberg, Germany. 
 # defaults { log_type = FILE /var/log/xinetd.log log_on_success = HOST EXIT DURATION log_on_failure = HOST ATTEMPT 
 # only_from = localhost instances = 60 cps = 50 10

In the above example, instances is set to 60.
You can update instances to the number of runtimes allowed by your license. Save the xinetd.conf file and restart the xinetd service for the changes to take effect.
