The only package installed from testing is nginx, and later gdb (to work with PIE binary) Backtrace follows (I installed libapr1-dev and dbg but gdb still says no symbol table for libapr-1.so)Thanks for the detailed bug report. I suspect this is may be a bug in mod_rpaf. Can you retry without it? The output of the following commands in gdb would also be interesting: f 1 p ap[i].x.ip p r->connection->remote_addr
Appreciate the swift reply. Have disabled mod_rpaf and am monitoring.
gdb commands follow:
