If a cache is configured in a way that trigger a WARN message the log message will not contain the cache name.
In case a template is used and/or multiple caches are configured that way the WARN message seems to be a duplicate and it is hard to track that down and fix (all) the problems - consider 10 messages like this and you might fix one but did not see a result as you don't count the messages.

Examples are
WARN [org.infinispan.CONFIG] (main) ISPN000564: Configured store 'SingleFileStore' is segmented and may use a large number of file descriptors
WARN [org.infinispan.CONFIG] (main) ISPN000403: No indexable classes were defined for this indexed cache; switching to autodetection (support for autodetection will be removed in Infinispan 11).

So it would be good to know which cache configuration is the cause of this
