Hi, Avi, sorry for not noticing this earlier. Some questions to assist in the
local reproduction of this problem:
- arch: x86-64?
- same script works in lkm (non-dyninst) mode?
- tried stap -p4 --dyninst FOO.stp ; gdb -args stapbpf FOO.so
so as to get a gdb backtrace at the crash site?
- what level of traffic is the httpd process absorbing during this time?
(thus: how much thread / child-process changes?)
- tried targeting a program other than this httpd?
