---------------------------------
Summary: HttpClient SelectorManager threads run indefinitely
causing OOM
Key: CXF-8885
URL: https://issues.apache.org/jira/browse/CXF-8885
Project: CXF
Issue Type: Bug
Components: Transports
Affects Versions: 3.6.0, 4.0.0
Reporter: Cardo Eggert
Attachments: image (5).png
Probably caused by https://issues.apache.org/jira/browse/CXF-8840 .
Started to notice that when updating from 3.5.x to 3.6.0 that our servers
started getting OOM. Noticed from the resulting logs that a lot of threads were
active that were in the format
HttpClient-<NR>-SelectorManager
when reverted to 3.5.6 then it did not occur anymore.
Tried to use VirtualVM when debugging it and saw when the thread was started,
it never died, basically meaning that it ran indefinitely. OOM happened when
there were about over 1000 of these threads.
