Hi,

I am new to the group, appreciate if you could answer a couple of queries I
have

Recently in one of my setups, I got this message continuously.

too many recvbufs allocated (40) - ntpd

I checked the code(ntp-4.2.0a) and found that ntpd has 40 recv buffers
allocated for the recv packets.

My questions:

1. What situation causes such syslogs to pop-up ?

2. Is it safe to increase the RECV_TOMANY to a larger value ?

Thanks
Kiran

How many servers do you have? What are your minpoll and maxpoll values for
those servers? Are you actually getting through to those servers ( what is
the output of ntpq -p).

I recall a bug like this being fixed a while ago.

4.2.0 is pretty old.  The latest stable release is 4.2.4, and we are pretty
close to releasing ntp-dev as 4.2.6.

I recommend you upgrade your ntp software.

Thanks for the responses. I will update to 4.2.4.
