-------------------------------------
Summary: Jetty QTP Thread leaks, may update Jetty to 9.4.42+
Key: SOLR-15518
URL: https://issues.apache.org/jira/browse/SOLR-15518
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 8.8
Reporter: Emmanuel Gosse
Hi,
As mentioned in this Jetty issue description,
[https://github.com/eclipse/jetty.project/issues/6323,]
I can attest that I met this bug in SolR 8.8.0 : index files locked (in DEL
mode : cf LSOF) by qtp threads staying in TIME WAITING forever.
As this threads won't recover if there is a constant load (a pause in the calls
allows qtp pool to free them), servers go to crash because of a memory leaks
that stay attached to this threads.
So good news, Jetty seems to have fixed it, I've tested with Jetty 9.4.42 and I
can confirm that I can't reproduce it anymore.
With all the successive upgrades of Jetty libs, it's difficult to determine
which Solr version
it started from.
Jetty 9.4.11 seems to be good.
Jetty 9.4.34 and 9.4.41 own the bug.
Emmanuel
