Possible problem with ntpd on NetBSD-5.0
Hello. We run a stratum 1 public time server under netBSD-4 which has
worked flawlessly for the past 18 months. It's used fairly heavily,
processing something on the order of 11,000 requests/second 24 hours a day
7 days a week.
Last night I attempted to update the machine to 5.0-stable, with less
than satisfying results.
the problem seemed to be that the ntpd kept grabbing more and more
memory, until it would exit with a memory allocation failure. Ntpd-4.2.4p2-o,
the version under NetBSD-4, runs happily in about 3mbytes of memory. The
4.2.4p6-o, which runs under NetBSD-5 wanted to grab more than a gig of ram
before dying because the machine has nothing more to offer.
It'spossible this is some sort of problem with the socket library,
since I also saw a lot of mbufs dedicated to ancillary data with netstat
While I try to figure out how to diagnose the problem, I've reverted
the machine to its former software load, and I thought I'd write to ask if
anyone has seen this problem with ntpd, and if they've been able to track
down where the problem is?
