I was testing on odhcp6c with the following commits:

     odhcp6c: update to 2020-12-01 version
    
     bcd86c748aeb script: handle possible issues with script termination
     031c39471396 cmake: fix out of tree building with libubox library
     a7b2221f6872 dhcpv6: avoid sending continuous renew/rebind messages
     d7afa2b6d31a dhcpv6: add extra syslog info traces
     f5728e40ff79 odhcp6c_find_entry: exclude priority from the list of fields that must match

FYI I've just updated to latest master with your commit 13734075d256
("odhcp6c: update to git HEAD") and it seems like the issue is back.
