This sort of thing can happen if the installed and running copies of the binaries are different, such as during a dnf upgrade, or perhaps during mismatches between containerized and host software versions. Perhaps the change occurred across a stap module compilation / run cycle. In case it is the last problem, try: # stap --poison-cache [...] By the way, can you share the contents of the /root/.systemtap/cache/7e/stap_7edbe3badfbf0f26279da1ce235*hash.log file? Hi Frank,
Thanks for your update and info as listed below.
