Mozilla processes TBs of Firefox crash reports daily using HBase, Hadoop, Python and Thrift protocol. The project is called Socorro, a system for collecting, processing, and displaying crash reports from clients. Today the Socorro application stores about 2.6 million crash reports per day. During peak traffic, it receives about 2.5K crashes per minute.

A peak of 40 crash reports per second and an average around 30 per second! I wonder what the distribution looks like for installs sending in crash reports. Are the majority of the reports coming in from a small portion of users or is it more spread out across the entire install base?
