Q1/2027 Server Maintenance
Description
mariadbd-multi treats two groups as a single server when their numbers exceed 18446744073709551615 (2^64 - 1), even if the numbers are different. Only one server is started, using the options from both groups. The second server is never started, stopped, or reported.
Test case
export PATH=/test/mtest/MDEV-42003/MD031126-mariadb-13.2.0-linux-x86_64-opt/bin:$PATH |

cat > /tmp/multi.cnf <<'EOF' |

[mysqld18446744073709551617]
|
socket=/tmp/b.sock |
