Upgrade to 3.1.0 fails when dhcpd.leases is from 3.0.4

Thu Mar 13 10:14:36 UTC 2008

Hi!

As a system integrator we currently run ~40 sites using ISC DHCPd. The 
Linux distro is Ubuntu 6.10 (not upgraded to later versions by different 
reasons).

I've successfully compiled and installed the 3.1.0 version on many of 
these sites, though some are running 3.0.4. (self-compiled)

We're installing a replacement-server for a customer, and during the 
setup of 3.1.0, we hit a show-stopper. The dhcpd.conf and dhcpd.leases 
used are from the existing system, which is running 3.0.4.
dhcpd.leases is what's causing the problem. Using a freshly touched 
dhcpd.leases, everything functions as it should. (using the existing 
dhcpd.conf). Trying to start dhcpd using the existing dhcpd.leases 
results in a

*** glibc detected *** /usr/sbin/dhcpd: munmap_chunk(): invalid pointer: 
0x080d7f47 ***
[snip]

I've read through the changelogs and see that are changes done to 
dhcpd.leases from 3.0.4 to 3.1.0, but can not find any information about 
special procedures to follow when upgrading.

The dhcpd.leases is 1.3MB.

I hope there's something "#¤"# simple step/limitation(?) I've overlooked..

Looking forward to your reply!

Best regards,
Ola
