[rrd-developers] crash - full hard disk

[Daniel.Pocock at barclayscapital.com]

As part of the scalability tests I've been doing, I regularly fill up my
hard disk with RRDs.

I've noticed that rrdtool (trunk, linked with Ganglia 3.1) creates one
or more files with size 0 or with other unusual sizes when the disk
fills up, and shortly after, there is a seg fault (gdb output below)

I wanted to create a ticket for this on the Trac system, but I couldn't
find the link for creating an account, and the account published on the
welcome page doesn't have permissions.



Program received signal SIGSEGV, Segmentation fault.
