Christine Poerschke commented on SOLR-15104:
--------------------------------------------
{quote}... require users to adjust their gc log housekeeping approaches?

SOLR-15281 proposes to introduce an optional {{SOLR_GC_LOG_FILE}} option which
could be set to {{solr_gc-%t.log}} or similar by the user.

> Reporter: Hongxu Ma
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h

> When restarting Solr, it will override the previous java gc log.
> This behavior is not friendly for debugging OOM, looks it is caused by the
> hard-code gc param (in bin/solr):

> Refer other sys, I think add timestamp in default gc filename will be better.
