why I did: after warm-reboot with all vlan members, syncd use memory up to 1.8g, and can not reduce to its normal state. what I did: this come from the glibc behavior, in the main heap, it almost not release memory to system, in apply view, huge memory used for compare logic, and do not use it again. so I add malloc_trim to release it.

How many clan members are in your case ? How did you counted that memory ?
