[SR-Users] random incorrect method parsing

can you change the sources and replace:
DBG(" method: <%.*s>\n",fl->u.request.method.len,
DBG(" method: <%.*s> (%d)\n",fl->u.request.method.len,
inside parser/msg_parser.c +625
Then recompile, reinstall and wait for same case again.
Maybe there is a '\0', although the logs are not showing it. Or the
length is not properly set.
