--------------------------------------
Summary: Protocok-okhttp: upgrade okhttp to 4.9.1 to address
infinite connection retries
Key: NUTCH-2890
URL: https://issues.apache.org/jira/browse/NUTCH-2890
Project: Nutch
Issue Type: Bug
Components: plugin, protocol
Affects Versions: 1.18
Reporter: Sebastian Nagel
Assignee: Sebastian Nagel
Fix For: 1.19
In rare situations and under heavy load (> 100 fetcher threads) I've seen that
the protocol-okhttp plugin gets into a state where a significant amount of CPU
time is spent in handling failed connections, see
[async-profiler|https://github.com/jvm-profiling-tools/async-profiler]
screenshot. This is caused by
[okhttp#5819|https://github.com/square/okhttp/issues/5819] which is fixed with
okhttp [4.5.0|https://square.github.io/okhttp/changelog/#version-450]).
We should upgrade to the okhttp 4.9.1 (the current stable version).
