Bakup file bug

[good2see]

I am running a shoutcast on ubuntu server.

Normally while there are 100-150 connected listeners, servers cpu load is 15%.

If I define a backup file into conf file, different bitrates then broadcast stream, server cpu loads anomaly. There must be a auto solution and prevention to this issue in shoutcast.

Versions:
Shoutcast DNAS/posix(linux x64) v2.6.0.753 (Apr 25 2019) on Ubuntu 20 x64

cpu loads: (you can see the two peak load while mispresented backup file.)
