OOM: Direct buffer memory

Hello,

After upgrading to Wicket 8.6.1 we started seeing periodical OOMs in
logs like below.
I'm not 100% sure that it's due to Wicket, but we didn't change
containers parameters and etc - so at least it's quite suspicious.
Our startup flags:
-XX:+PerfDisableSharedMem -Xmx4G -Xms4G -XX:MaxDirectMemorySize=4G
-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=/app/runtime/heapdump.bin

Btw, except these exceptions in logs - no other negative effects (at
least we didn't reveal so far).

If you have ideas - I will really appreciate.

java.lang.OutOfMemoryError: Direct buffer memory
 at java.nio.Bits.reserveMemory(Bits.java:666)
 at java.nio.DirectByteBuffer.<init>(DirectByteBuffer.java:123)

Wicket users,

We are still investigating, but it's seems to be related to using of
docker image with openjdk over alpine.
If you have similar situation: try to repack under different base
docker image with java.

Yes. Pretty sure.
But it might be something indirect: for example, during building of our
next docker image with the newer wicket, some openjdk/maven/libs newer
dependency was picked up as well.
That's something which we are evaluating.

Thanks,
Ilya

Hi,

I don't see anything related in the changes from 8.5 to 8.6.1

https://github.com/apache/wicket/blob/wicket-8.x/CHANGELOG-8.x

Are you sure these OOMs didn't happen before?

Sven

Sven,

It was 8.5 - so not so far away.
