We have a strange thing happening on our BCM 4.0 system. The other day it ran out of memory and we got a critical alarm saying so. Shortly after that occurred we noticed that when we dial a "9" we get a fast busy with no message. This has been working and we have destination code 9 set to route 000 which uses pool "A" and there are lines assigned to Pool A. Nothing appears to be setup wrong and have compared to working systems and they are the same. Anyone have any suggestions as to what could cause this. I only mention the memory problem since these things have not happened before and they are within a day of each other.
