I have a script that collects SNMP information on a bunch of routers that continues to seg fault on me about 10-25 % of the time.

It creates an array of Net::SNMP objects and then steps through that array, querying each router for certain information and then writing it all out to an RRD file.

I have it doing some minor logging, but since it runs on a crontab I've never actually seen it seg fault. I believe it's doing it during the gather phase, but I'm not sure.

My longwinded question is, is there any way I can track down what's causing this or at least where it's happening ? I've tried to throw some eval statements, but that doesn't stop the segmentation fault

BTW, I'm running it on a FreeBSD 3.4 box with 512Mb of RAM. The box is rather busy, so could it be a lack of memory issue ?

Any help at all would be greatly appreciated.
