Clean up cache before insmod vrouter According to [1] vrouter uses kmalloc. This means there should be a 300MB of contiguous memory block. Dropping cache is official recommendation for Juniper according to [2]. That increases a chance to have such chunk. It's very important for compute nodes with small amount of RAM or nodes with a lot of allocated resources for other purposes (ctl + ntw) combination for instance.
