Hi to all
I am facing a problem with the corruption of the dhcp lease file
causing problems to many users.
We use the dhcp server to serve cable modems. We use CASA CMTS
C3200 & C40G
We got this log from the dhcp server.
Sep 18 04:17:15 dhcp1 dhcpd: /var/lib/dhcp3/dhcpd.leases line
113920: expecting left brace.
Sep 18 04:17:15 dhcp1 dhcpd: uid "\
Sep 18 04:17:15 dhcp1 dhcpd: ^
Sep 18 04:17:15 dhcp1 dhcpd: /var/lib/dhcp3/dhcpd.leases line
113920: possibly corrupt lease file
Sep 18 04:17:15 dhcp1 dhcpd: uid "\377;-E\\\\5;
Sep 18 04:17:15 dhcp1 dhcpd: ^
Sep 18 04:17:15 dhcp1 dhcpd: Corrupt lease file - possible data
loss!
Sep 18 04:17:15 dhcp1 dhcpd: Corrupt lease file - possible data
loss!
Sep 18 04:17:17 dhcp1 dhcpd: Wrote 0 class decls to leases file.
Sep 18 04:17:17 dhcp1 dhcpd: Wrote 0 deleted host decls to leases
file.
Sep 18 04:17:17 dhcp1 dhcpd: Wrote 0 new dynamic host decls to
leases file.
Sep 18 04:17:17 dhcp1 dhcpd: Wrote 8771 leases to leases
file.
2 hours before we had this log :
Sep 18 02:43:35 dhcp1 dhcpd: Wrote 0 class decls to leases file.
Sep 18 02:43:35 dhcp1 dhcpd: Wrote 0 deleted host decls to
leases file.
Sep 18 02:43:35 dhcp1 dhcpd: Wrote 0 new dynamic host decls
to leases file.
Sep 18 02:43:38 dhcp1 dhcpd: Wrote 104799 leases
to leases file.
Clearly when the lease file got corrupted it caused the lease to
drop from 104799 leases to
8771 which created us a lot of
problem with the customers.
This problem happened again but in a different dhcp server and it
had the same nature of logs.
We are afraid that this may happen again !
Is this a bug of this version 3.1.1 and is it solved if so ?
If i have to upgrade are there any stable versions ?
I want to be assure that there are no problem with option 82 (
relay agent ) ?
I can't afford to risk on live implementation .
Many thanks
Endrit Hasaj
