Hi Iñaki,

this would be possible, but its IMHO a bit wrong from a conceptional POV. This 
FIFO command execution belongs to the MI process, and it should not affect the 
working of other process which are busy routing SIP requests - they don't need 
to see this as all. One workaround is as discussed is to just use system 
malloc, another would be to partition the command execution in small steps 
like we do for data loading in several modules.

But as i said earlier, its maybe not the best idea in general to pipe the 
output of several houndred thousands rules through the MI interface, 
especially if the information is available more or less similar in the 
database.

Regards,

Henning
