Code: 
"core file may not match specified executable file."
normally shows up when you run gdb to debug the core file and there is a mismatch between specified executable file and core file.

Did you run such debug? Any core dump file generated?

Some more info:
To solve another issue I upgraded from 1.3.5 to 1.3.10. I'm still getting the core file errors above in stderr.log just like before.
I ran 'ls' inside /tmp/lshttpd to see what was inside
bak_core lshttpd.pid lsphp5.sock lsphp5.sock.108 lsphp5.sock.172 lsphp5.sock.540 lsphp5.sock.730 lsphp5.sock.983 swap

not seeing any core files.

also, since the upgrade. I'm getting emails about once a minute with this message at the top:
web server with pid=10691 received unexpected signal=11, a core file is created. A new instance of web server will be started automatically!

followed by:

Server: LiteSpeed/1.3.10 Open

OS: Linux

Release: 2.6.32-431.23.3.el6.x86_64

Version: #1 SMP Thu Jul 31 17:20:51 UTC 2014

Machine: x86_64


If the call stack information does not show up here, please compress and forward the core file located in /tmp/lshttpd/.

Do I need to recompile PHP since the upgrade?
