QUESTION
I am building Docker image with the spring-boot-maven-plugin that is deployed to AWS BeanStalk. I use the plugin through the 2.4.3 spring boot starter dependency) However, when the container is started, I get the error below. I am a bit new in the buildpack stuff, but tried to solve it by playing with the Buildpack env variables as described on the website. But it had absolutely no effect on the values shown in the error log below. I found this github issue but not sure if it's relevant and how to use it.
I am using AWS Micro instance that has 1G total RAM, it performs a rolling update, so at the time of starting the new image, the other is also running till the new one started with success, so to start the container could as well be that only 300MB is available, however, during normal run it has more available.
Why do I need this memory calculation? Can't I just disable it? When I build a Docker image of the app.jar and deploy it to aws beanstalk, it works well without any memory settings:
docker build . --build-arg JAR_FILE=./target/app.jar -t $APPLICATION_NAME
But I would love to use the image build through the spring-boot-maven plugin. Please some advice on how to solve this?

Answered 2021-May-19 at 01:58OK, so here's what this is telling us:
Calculating JVM memory based on 274300K available memory
The memory calculator is detecting a maximum amount of memory available in the container as 274300KB, or about 274M.
fixed memory regions require 662096K which is greater than 274300K available for allocation: -XX:MaxDirectMemorySize=10M, -XX:MaxMetaspaceSize=150096K, -XX:ReservedCodeCacheSize=240M, -Xss1M * 250 threads
This message is saying that the memory calculator needs at least 662096KB or 662M in its present configuration.
It's also breaking down why it needs/wants that much:
- 10M for direct memory
- 150096K for metaspace
- 240M for reserved code cache
- 250M for threads (thread stack specifically)
That's not counting the heap which will require more (you seem to want at least 1G for the heap).
This leaves two possibilities:
- The container is not provisioned large enough. You need to give it more memory.
- The memory calculator is not correctly detecting the memory limit.
If you suspect #2, look at the following. The memory calculator selects it's max memory limit (i.e. the 274M in the example above) by looking in these places in this order.
- Check the configured container memory limit by looking at
/sys/fs/cgroup/memory/memory.limit_in_bytesinside the container. - Check the system's max available memory by looking at
/proc/meminfoand theMemAvailablemetric, again, from inside the container. - If all else fails, it'll end up with a 1G fallback.
If it's truly not working as described above, please open a bug and provide as much detail as you can.
Alternatively, you may tune the memory calculator. You can instruct it to give less memory to specific regions such that you reduce the total memory required to be less than the max available memory.
You can do that by setting the JVM memory flags in the JAVA_TOOL_OPTIONS env variable (you have BPE_JAVA_TOOL_OPTIONS which isn't right). See https://paketo.io/docs/buildpacks/language-family-buildpacks/java/#runtime-jvm-configuration.
For example, if you want to override the heap size then set -Xmx in JAVA_TOOL_OPTIONS to something custom. The memory calculator will see what you've set and adjust the remaining memory settings accordingly. Override as many as necessary.
To get things down to fit within 274M of RAM, you'd have to go really small. Something like -Xss256K -XX:ReservedCodeCacheSize=64M -XX:MaxMetaspaceSize=64 -Xmx64M. I didn't test to confirm, but this shows the idea of what you need to do. Reduce the memory settings such that the sum total all fits within your max memory limit for the container.
This also does not take into account if your application will actually be able to run within such small limits. If you go too small you may at some point see OutOfMemoryErrors or StackOverflowErrors, and your app will crash. You can also negatively impact performance by reducing code cache size too much since this is where the JIT stores byte code that it's optimized to native code. You could even cause GC issues, or degraded performance due to too much GC if the heap isn't sized right. In short, be very careful if you're going to do this.

Answered 2020-Dec-08 at 15:47I found the answer here:
A short time after the screen turns off while the device is on battery, Doze restricts network access and defers jobs and syncs.
I overlooked this, as it is not explicitly mentioned on the main Doze guide in the documentation, which still insists that the device should also be stationary to enter Doze:
If a user leaves a device unplugged and stationary for a period of time, with the screen off, the device enters Doze mode.

I have a table like this:
...ANSWER
Answered 2020-Nov-27 at 20:45SQL tables represent unordered sets. SQL results sets are unordered, unless there is an explicit ORDER BY corresponding to the outermost SELECT.
Period.
If you don't have an ORDER BY, you should have no expectations on the ordering of the results. The ordering can change from one run to another.
And, even if you have an ORDER BY, if you have ties (i.e. keys with the same values), then they can be ordered arbitrarily from one run to the next.

I have a string that contains sentences. If this string contains more character then a given number. I'd like to split up this string into several strings with less then the max number of character, but stil containing full sentence.
I did the below, which seem to run okay, but not sure if I will experience bugs putting this in production. Does the below look okay?

We want string of max len=15, i.e. 1520 in this case is 16. As you can see first 3 items in the list are 5 + 6 + 4 = 15, so, fisrt shortened_sentence should consists of first 3 items in the list. but it does not. because the logic of the second if is incorrect.

Answered 2020-Jul-08 at 02:34Success! Not a permanent configuration but a good enough workaround - this article gave the answer on how to stop the container manually, then it was just a case of running a deploy.
Steps were:
- SSH to the ElasticBeanstalk instance with
eb ssh -i. sudo stop eb-dockerto tell Upstart to stop the container.docker psto verify that the container's no longer running.- Carry out the EB deploy as normal.
