[FROG] high cpu usage because of 100s of ping to ospf peers by user frr

Hi, i'd got a basic setup of ospf with 5 6 ospf neighbours. Everyon now and then there is very high cpu usage. Htop shows 100s of ping to ospf peers by user frr (just 5 to 8 peers). Other peers are mikrotik. Makes the system instable till kill all the pings. Its a pppoe server with 4000+ pppoe interfaces. Kindly help in resolving the problem. -- Thanks and Regards
