### dropins
# 2026-08-18: proxy wedged after 14d uptime — accept() returned EMFILE at the
# systemd default soft limit of 1024 fds (1016 sockets, 547 in CLOSE-WAIT),
# the 1024-deep accept backlog overflowed, and every PBS client timed out.
# ~85k requests/day against this endpoint; 1024 is not a sane ceiling for it.
[Service]
LimitNOFILE=65536
# 2026-08-18: raised alongside the proxy (see its 20-nofile.conf). This daemon
# was NOT the one that exhausted fds (it held 15), but the systemd default 1024
# is not a sane ceiling for a PBS backend either.
