[pkg-dhcp-devel] Bug#888209: isc-dhcp-client: hammers DHCP server if it cannot write lease file

[Toni Mueller]

Package: isc-dhcp-client
Version: 4.3.5-3+b2
Severity: normal


Hi,

I recently experienced a problem with dhclient issuing a ton of requests
in rapid fire mode in an endless loop because the file system where it
wanted to write its lease file, was mounted read-only. It got a new IP
everytime and added them all to the interface. It would be nice if
dhclient could just be content with having one IP address, and then stop
asking until the lease expires, regardless of the state of the file
system, instead of issuing dozens of DHCP requests per second.

I experien


Cheers,
