Noticed that the logs on that host are flooded with this one message:
fpc0 PFE Statistics received unknown trigger (type Semaphore, id 0)
at about 300k logs/h.
It's less visible on the cli as they're aggregated with:
Jul 2 11:30:22 lsw1-a8-codfw fpc0 PFE Statistics received unknown trigger (type Semaphore, id 0) Jul 2 11:30:25 lsw1-a8-codfw last message repeated 273 times Jul 2 11:31:22 lsw1-a8-codfw last message repeated 4692 times
But much more visible on the Opensearch collector.
No clear pointers on a quick web search. Either we upgrade, or open a JTAC, or reboot.
