Eigler changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |fche at redhat dot com --- Comment #1 from Frank Ch. Eigler --- Nice analysis. I suspect the problem originates from the setup_timeout() code that impleme= nts the stap -T NNN function. Its join_group etc. stuff was probably buggy, and was copy-pasted into the monitor-related synthetic probe stuff. I think the right fix there is to drop the dp->join_group(s); in each of th= ose clones, because synthetic derived_probe objects are joined at the other area you found. --=20 You are receiving this mail because: You are the assignee for the bug.=
