How to set MAX N PID

[davidfstein]

The max pid is incorrectly set. In previous issues there is a suggestion that max pid can be set as an environment variable, but there is no documentation of what this variable should be anywhere nor what version of t_coffee supports this behavior. When t_coffee complains about the max pid it says to set the variable and recompile, but again there is no indication of how to achieve this. How can we properly set the max pid?

I got the same error, but don't know how to solve it.

I also encountered this problem. See this comment for a solution that works in Ubuntu, and hopefully in all Linux systems.
