question: Will this create too many allocations.

it's not supposed to fail the cache acccess. Note that this method is on the hot path when finish is called on the root span -> write is called. If this throw we might bubble the application code IMO. Better to allocate something than throw

Is the failure constant on Semeru? Or is it sporadic?
If it is constant, we should probably detect the failure and then just bypass the cache there after.
I've started debating using UTF8BytesString for values, since we now have the UTF8 cache. I also have some evidence that some caches are doing more harm than good now.
Long term, I'm hoping that TagMap will provide a more elegant solution to these problems, but unfortunately, I'm not there yet.

well I think more that there are no failures in the real life but only happens in CI. The stacktrace is very weird since it sounds like implying that either unsafe is null (sounds impossible) either the array is itself is null (that sounds not possible as well unless the class is unsafely allocated). In CI it passes on a retry run on a fresh JVM that looks indicating that something is gets corrupted on the used jvm? I put this catch in a defensive way - I can remove if needed

How many semeru 11 hosts can be impacted ?

Just curious if we can use int here too? Same as you did with port?
Or it would be a huge refactoring?

Indeed I think it can be just an int (I see we use a short indeed) since in other parts is casted as int
