During the execution of some of the scripts in multi-VU cases,
one of the VU would stuck on DO_FreeHttp() call close to the end,and all the VU after that one in the same script would stuck on whatever they are doing, and no timeout errors, no nothing after that happens.

I tried commenting out DO_FreeHttp(), the problem went away.
But I can't find enough information to fully determine seriousness of leaking and other possible side effects of commenting out DO_FreeHttp().

Has anyone seen this problem? any advice?
