Good morning, same problem, and it seemed strange to me that until now no one else had reported it 😊 . Some more info:
* The problem seems to have appeared in the change of version from 11.1 to 11.2. I don't know if it can hit something but in the jump between version 10.3 and 11 I also changed operating system from centos7 to debian. In the jump from version 11.1 to 11.2x I saw that there was some small change in the executable that manages the dhcp service https://fossies.org/diffs/packetfence/11.1.0_vs_11.2.0/go/cmd/pfdhcp/main.go-diff.html * The problem seems to appear when PF tries to use the first address of the pool, which it generates is XXX.XXX.XXX.10. In the Serhiy log we read the IP 192.168.32.10, while in my logs I read 10.0.5.10 because I use the 10.0.5.0/24 network. This does not happen after restarting the service. Does one of the changes of the executable between versions 11.1 and 11.2 concern the management of the first address to be released? * the problem is very subtle because it does not appear immediately after the service starts and when the system enters this loop if I restart the dhcp service everything returns to work * I have 3 locations with standalone installations, all with 11.2 and in all three I have the same problem. * For now we are proceeding with some workrounds such as periodic restarts of the dhcp service through the cron or on other locations by regenerating the arp table more frequently (lowering the value of neigh.default.gc_thresh from 128 to 64 ☹) I hope I have added some useful details to the solution. thanks and bye Giacinto Caretto */*/*/*/*/*/*/*/*/*/*/*/*/*/*/ Giacinto Caretto.
