- Subject: Problem using bulk mode (relayfs)
I am having trouble running stap in bulk mode on a script that otherwise
works fine. That is, I normally run with just "-g" but with "-g -b" it no
longer works. Here's the output with one -v. Is this a known problem?
OS version: 2.6.16 modified with various real-time patches
stap version: (version 0.5.13 built 2007-02-12) (Using Red Hat
elfutils 0.125 libraries.)
Pass 1: parsed user script and 54 library script(s) in 260usr/0sys/269real
ms.
Pass 2: analyzed script: 6 probe(s), 14 function(s), 3 embed(s), 0
global(s) in 300usr/60sys/356real ms.
Pass 3: using cached

Pass 5: starting run.
insmod: error inserting

Pass 5: run completed in 0usr/10sys/30real ms.
Pass 5: run failed. Try again with more '-v' (verbose) options.
Increasing the level of verbosity generates no error/warnings in Passes
1-4 and no additional output in the failing Pass 5.
