Here, developers ...

8.3.1. Mem_limit index process memory usage restrictions. Optional option, default 32M. This is a mandatory memory limit that indexer does not exceed. Can be in bytes, kilobytes (with K), or megabytes (with a suffix of M). See examples. This limit is automatically increased when a value that is too small causes the I/O buffer to be below 8KB, and the minimum value depends on the size of the data to be indexed. If the buffer is below 256KB, a warning is generated. The maximum possible limit is 2047M. Too low values affect index speed, but 256 ...

So here are some guidelines for how to report bugs. Build-time problems if the Sphinx build fails, please: 1. Verify that your DBMS's header and library files are installed correctly (for example, check ...).
