dhcpd start failure - dhcpd.leases: file is too long to buffer
Environment
- Red Hat Enterprise Linux 6
- dhcp-4.1.1-61.P1.el6_10
Issue
File /var/lib/dhcpd/dhpcd.leases
grows indefinitely which then leads to dhcpd
crash upon start:
/var/lib/dhcpd/dhcpd.leases: file is too long to buffer
Resolution
Update to dhcp-4.1.1-63.P1.el6_10
shipped with Advisory RHBA-2018:2900 or newer.
Root Cause
Previously, the DHCP
server process tried to allocate memory for the dhcpd.leases
file to load it. As a consequence, the DHCP
server process terminated unexpectedly. With this update, when the replay mode is disabled, the DHCP
server process does not try to allocate memory for the whole dhcpd.leases
file, and the described problem no longer occurs.
