The solr.in.sh file included with Solr does NOT have GC_LOG_OPS or
GC_TUNE defined, so those had to have been added by whoever set up your
Solr install.
You should remove them entirely and let Solr use its default settings
for GC logging and GC tuning, unless you would like to switch to ZGC, in
which case you can use the GC_TUNE that I provided elsewhere in this thread.
Thanks,
