What is stringHighUse4K? Not much explanation on the internet, but
there are references to some PTF's.

The F/program in that scenario is immaterial; just ignore that. It is the name of the LIC module that implements the HLL statement; most likely a test or copy instruction that implements the op-code\request identified as the statement 12400. That same LIC program name would appear generically across /many/ unrelated incidents of failing user-code [as well as system-code].

What is relevant, is what storage is being addressed in the failing HLL instruction\statement, and why the offset used in reference to that storage is invalid\out-of-bounds whilst the program LOGGINGPROGRAM in LIBRARY is running in the job [in that case JOB(732150/QUSER/QRWTSRVR)].
