Subject: [PATCH] Set cap on JDK per-thread native byte buffer cache
|
|
|
|
See: https://www.evanjones.ca/java-bytebuffer-leak.html
|
|
|
|
This is potentially a source of lots of native memory usage.
|
|
|
|
We are clearly seeing native usage upwards to 1-4GB which doesn't make sense.
|
|
|
|
Region File usage fixed in previous patch should of tecnically only been somewhat
|
|
temporary until GC finally gets it some time later, but between all the various
|
|
plugins doing IO on various threads, this hidden detail of the JDK could be
|
|
keeping long lived large direct buffers in cache.
|
|
|
|
Set system properly at server startup if not set already to help protect from this.
