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=20=20=20
  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?
