it looks like u-boot allocates a buffer of CONFIG_ENV_SECT_SIZE size when making "saveenv" command. In our case CONFIG_ENV_SECT_SIZE is 128Kb, so having CONFIG_SYS_MALLOC_LEN = (128Kb + space for environment) is not sufficient.
Increase CONFIG_SYS_MALLOC_LEN to (196Kb + space for environment) to resolve a problem.
