A colleague from a different department was managing a fleet of servers doing a lot of computing. Their BMCs would just stop working after a few weeks of uptime, every time. He was annoyed by it but mostly ignored it as it was mostly just used for additional monitoring. The power outlets in the racks were remote controllable, so you could still hard reset a server if this was required.

However, as this fleet was used for computation, after a while they noticed that whenever the BMC stopped working, performance of the system increased by almost 10% or so. Definitely a non-neglible amount. So they kept the machines running in the broken BMC state for as much as possible.
