Invalid binding state transition: active to expired

[Jim Liang]

Hi,

I'm using ISC DHCP Server V3.1.0
We're facing an error in the log file as below:
Sep 13 12:09:03 2010 PSCDHCPD-E-Received BNDUPD resulted in - 10.34.150.172: invalid state transition: active to expired

I checked "DHCP handbook" and found that, this error is a lost lease bug in ISC DHCP SW, refer to below:
Lost Leases
With the ISC server, it's sometimes possible to get into a state where, because of software
bugs, particularly in older versions, the lease databases are not in sync. This sort
of problem can persist even after you upgrade to a newer version of the server
without the bugs. The usual symptom of this is log messages such as "Peer holds all
free leases" and "No free leases," when you know there are plenty of available IP
addresses.Another symptom of a lost lease is that a client always gets leases that are
the MCLT long, even though the servers are operating in the NORMAL state. The
message "Invalid binding state transition: active to expired" might indicate that the
server still has this bug.
It might also indicate some other problem.

Can anyone tell me if this bug has been fixed? In which release it been fixed?
Or how to check the ISC DHCP bug report/status? Any web link?

Thanks in advace!
BR//Jim
