Does you application or any your libraries use JNI? The crash might be originated from the native code.

Hi @eastig,

Thankyou for the update. When i debug using gdb I could see the failure is happening with the below library

Hi @eastig,

Please see some more information.

Here we build this application in 32-bit java 1.8 jdk

Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) Server VM (build 25.201-b09, mixed mode)

and we run this application in 64 bit amazon corretto jvm

openjdk version "1.8.0_382"
OpenJDK Runtime Environment Corretto-8.382.05.1 (build 1.8.0_382-b05)
OpenJDK 64-Bit Server VM Corretto-8.382.05.1 (build 25.382-b05, mixed mode)

Is there any compatibility issue here

[eastig]

Is there any compatibility issue here

Nope.

BTW, you are using a very old build of Corretto 8: 8.382.05.1. The latest is 8.412.08.1. Can you try the latest one?

[apancorb]

Hi @eastig,

I am getting the same error. I am using 1.8.0_412-b08. The strange part is that this was not happening a month ago.

Here is the log file: hs_err_pid2525.log

[eastig]

Hi @apancorb,
Your crash might be different from the one reported by @anup60.
Do you have a reproducer?
Your JVM options:

jvm_args: -XX:MaxMetaspaceSize=256m -XX:+HeapDumpOnOutOfMemoryError -Xms256m -Xmx512m -Dfile.encoding=UTF-8 -Duser.country=US -Duser.language=en -Duser.variant

Can you make Xms and Xmx having the same value? If it does not work, can you also add -XX:-ReduceInitialCardMarks ?
