LSA disappeared

[Eugene M. Zheganin]

Hi.

I got rid of quagga on one of my largest UNIX router, now the log is
filling with 'LSA disappeared' messages. Not that it's a huge problem,
but how do I get rid of them ? This doesn't look like a network problem
or protocol misconfiguration, for example, when an pptp link goes down
on a neiboring bird router, I got 'LSA disappeared' about this pptp link
on this one. In the same time having

log syslog {
    warning
};

looks pretty enough for me.

or does this message mean that it's some sort of problem ?


Thanks.
Eugene.
