Hi Blake,
for outbound prefixes, i am using prefix-list filter which is identical at my side and UP Link side. for inbound prefixes , i have set max-prefix at maximum value because i am receiving full BGP table from my UP Link. entities of prefix-list has configured in this form x.x.x.x/y le 24, it might be many prefixes are passed within this range. But this issue is happen sometime, really strange.
