morning.

hey all, have been playing around with Anglican lately, but I have run into a snag: multithreading seems to get throttled after 20 minutes of CPU time.

So when I am observing top, the CPU % hovers around 900-1000 then promptly drops to 100% after 20 minutes, pretty much every time.

Does anyone know what may be causing this? I suspect it could even be JVM options but I have not even the first clue how to debug this one...

@djtango We use this (with large hat tipping to @tcoupland @elise_huard and @acron )

: ${PEER_JAVA_OPTS:="-Daeron.term.buffer.length=33554432 -Xmx${XMX}m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=$SANDBOX -XX:ErrorFile=hs_err_pid_%p.log -XX:+UseG1GC -Xloggc:gc_%p.log -XX:+PrintGCCause -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=3 -XX:GCLogFileSize=2M -XX:+PrintGCDateStamps -server"}

That will give you an idea of heap/gc. Also worth opening up JMX port and running jconsole against the application.

And you can ignore, -Daeron.term.buffer.length=33554432, I need that one only

Wow thanks, @jasonbell

@djtango - Thank @tcoupland @elise_huard and @acron, they showed me 🙂

:) awesome thanks guys!

@djtango just to confirm then you'd run java $PEER_JAVA_OPTS -cp myjar.jar path.to.class.main etc

🙂 thanks, will admit had to lookup github

no proble

Does anybody else find themselves modifying the pages they're on when they find bugs? Just randomly browsing the web, notice that the content seems cut off, so I go & tweak the css to fix the bug. Chuckling to myself about how the css dev didn't consider that 200vh wouldn't be enough for all content on the site! I often borrow my girlfriends laptop and do this when she's confused by a page.

Haha, yes, I find myself doing that too from time to time

i especially do it when i’m printing a recipe
