Thank you for running a Snowflake proxy. The high bandwidth usage is not abnormal. If you want to limit or reduce it, you can try different settings of the [`-capacity` command-line option](https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/blob/5dd0a31d95052eca7e89cef8ccc527b74a1c6be5/proxy/README.md#running-a-standalone-snowflake-proxy). The default is unlimited; you might try `-capacity 10` and adjust from there.

The (currently) two Snowflake bridges together transfer 100 GB about every 2 minutes, on average. So while 100 GB in 24 hours for one proxy seems like a lot, it is still just a small part of total Snowflake traffic.

I’m sorry that the proxy is crashing and restarting. It is probably a bug in resource management. You can read more at the below thread and issue:

> I run about 30 Snowflake proxies on various IP addresses. They are all docker containers and generally each proxy gets about 360-400 connections per hour and relaying an average of 1GB per hour. They’ve been running mostly smoothly until recently. For the past few days, They have started to consume a huge amount of RAM and I’m getting huge spikes in CPU. They consume all the RAM I give them whether it be 1GB or 7GB of RAM and start crashing and restarting one by one. What’s interesting is that…
