Hi,  
While calling nginx stop we are getting following error:  
[alert] 25563#0: waitpid() failed (10: No child processes)

What could be the reason for this problem?  
How can we solve this? or Can we ignore this error ?  
regards  
Vivek G.

Yes, this error is already logged at “info” level for Solaris  
and FreeBSD and probably should not be logged at all.  
What OS do you use?
