[OpenSIPS-Users] Strange segfault when calling check_fraud

[Liviu Chircu]

Hi, Jim!

It appears that OpenSIPS is either getting restarted too quickly or runs 
out of disk space before it is able to fully write the 3 GB corefile. If 
the size of your drouting data allows it, you could reduce the corefile 
size by shrinking the shared memory pool OpenSIPS starts with.
