Fixed In:

Very large gem TOC disables native code

Using a very large setting for GEM_TEMPOBJ_CACHE_SIZE, 10GB or larger, results in issues for the native code generator, which reports the warning message:
  native code DISABLED, offset from code memory to libgcilnk.so exceeds 32bits

In 3.2.x, this caused logins to fail with the error
   Fatal error in native code generation, emit_call_stub, jmp displacement exceeds 32bits Error Category: [GemStone] Number: 4151 Arg Count: 1

Workaround

In 3.2.x, reduce the GEM_TEMPOBJ_CACHE_SIZE to less than 10GB, or disable native code generation by setting GEM_NATIVE_CODE_ENABLED = 0;

The warnings in 3.3.x and later can be ignored, although there may be performance differences in the absence of native code generation.
