# victoriametrics 1.59 with ~7GB of data seems to eventually panic when merging files and then
# begins restart-looping forever. Set LimitNOFILE= to a large number to work around this issue.
#
# panic: FATAL: unrecoverable error when merging small parts in the partition "/var/lib/victoriametrics/data/small/2021_08":
# cannot open source part for merging: cannot open values file in stream mode:
# cannot open file "/var/lib/victoriametrics/data/small/2021_08/[...]/values.bin":
# open /var/lib/victoriametrics/data/small/2021_08/[...]/values.bin: too many open files
