Hi
I am running into an interesting garbage collection issue and am looking for
suggestions/thoughts.
Because some word lists such as synonyms, plurals, protected words need to be
updated on a regular basis I have to RELOAD a number of cores in order to 'pick
up' the new lists.
What I have found is that I get a memory leak when I do a RELOAD rather than an
UNLOAD/CREATE with core admin. This is most pronounced with the G1 GC and much
less so with the CMS GC. The former will cause the VM to run out of memory
after 5/6 RELOADs, while the latter does so after 30/35 RELOADs. We are not
talking about large indices here, the files footprint totals 470MB.
I am using SOLR 4.8.1, Tomcat 7.0.53, jdk1.7.0_60, on Fedora Core 20. I am not
using any fancy GC parameters, I cut everything back to basics, just:
-Xmx1G -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
and
-Xmx1G -XX:+UseG1GC
I was curious if anyone else had run into this issue and managed to fix it?
Thanks
François
