There are two versions of the lshttpd binary shipped in the LSWS Enterprise package. One is the release build. The other is the debug build. The debug build is not normally used when you run LSWS, but, when debugging, the GDB stack backtrace and core file generated by the debug build are the most useful information you can provide for fixing the bug.
These two builds are shipped in the distribution package as:
The release version is installed as “lshttpd.<version>”, while the debug build is installed as “lshttpd.dbg.<version>”. In order to use the debug build (and produce the data that will allow us to more effectively debug your issue), you need to switch to the debug build manually:
