I've run the straced JVM (OpendJDK 11):
strace -e trace=mmap java -Xms8192m Main

I set the initial size of the heap to 8192M and I tried to find allocation of the heap in the output of the strace. I could not find it. Why?
Add -f option (Trace child processes).
Running Java code in a primordial thread used to cause many problems, see JDK-6316197 for details.
java launcher creates a JVM in a new thread.
My application is based on Micronaut and GraalVM (java 11) and does a simple call to http://httpbin.org/get:
#Controller("/api")
class HelloWorld(
#Client("http://httpbin.org")
private val httpClient: RxHttpClient
) {
private val logger = LoggerFactory.getLogger(javaClass)
#Get("/hello")
fun hello(): String {
return "Hello World!"
}
#Get("/fb")
fun fb(): Flowable<String> {
logger.info("Trying to call FB")
logger.info("Using url http://httpbin.org/get")
try {
return httpClient.retrieve("/get")
.doOnError { logger.error("Error calling fb api flowable", it) }
.doFinally { logger.info("Finished calling FB api flowable") }
} catch (ex: Exception) {
logger.error("Error calling fb api", ex)
throw ex
} finally {
logger.info("Finished calling fb api")
}
}
}
When I build a docker image of the app using this Dockerfile:
FROM maven:3.6.3-jdk-11 as maven
COPY . /home/app
WORKDIR /home/app
RUN mvn package
FROM oracle/graalvm-ce:19.3.1-java11 as graalvm
COPY --from=maven /home/app/target/app-*.jar /home/app/
WORKDIR /home/app
RUN gu install native-image
RUN native-image --no-server --enable-http --enable-https -cp app-*.jar
FROM debian:stretch
EXPOSE 8080
COPY --from=graalvm /home/app/app .
#RUN apt-get update && apt-get -y install strace
ENTRYPOINT ["./app"]
Everything works in my local environment.
But when I push the image to Google Cloud Repository, deploy it to Cloud Run and try to access the endpoint /api/fb, it crashes the container with 503 Service Unavailable.
The error in the logs is "The request failed because the HTTP connection to the instance had an error.". When I enable strace, these are the logs:

I tried using a different library to make the call, Java 11 Http client, and it works. But whatever I do, it doesn't work when I use Micronaut Http client, and there is no helpful message.
I also tried using Java 8, a different linux distribution in the docker image (fedora:latest, ubuntu:latest), but it didn't help.
Do you have any idea what could be causing this?
Thanks for you answer in advance.
ok. Since this is the only question that comes up whenever someone searches for cloud run 503 error, I would like to share my horrible experience and solution.
I deployed my spring boot app on cloud run and configured pub-sub push subscription trigger for it. I tested it on my local system. Then i tested it on my private GCP project. And then when i deployed it on my organization's GCP account, I started to get 503 error.
After this, below is what i tried.
I tried changing the roles/permissions of the default service account (which was used by the run instance) by giving max permissions, but it was of no use.
Tried changing the concurrency to 1 (as suggested in GCP docs) but no help.
I started comparing each and every config of my run instance with my private GCP run instance, And then i found out that I mistakenly had checked below option which was causing this issue.
So i unchecked it, redeployed my instance, and it worked.
In my case I simply made a syntax error in my python code inside my Cloud Run instance and I got the 503 Service Unavailable error.
This showed up in the logs. Go to your Cloud Run Service and click "Logs" for more details.
So it looks like the core of the issue is that Cloud Run currently does not support HTTP streaming:
https://cloud.google.com/run/docs/issues#grpc_websocket
And when I return Flowable with Micronauts, it is opening a streamable HTTP connection. So the solution is not to use Flowable (or any other Publisher that is unbounded e.g. Flow, Flux etc) as a response.

(Posted on behalf of the OP).
I dont know exactly how, but it's solved... maybe reinstalling libapache2-mod-php7.0 was the failure.
I'm trying to run autossh (on a VM running CentOS6), but it's exiting immediately with the help message. I think this is a system issue because when I run it with the exact same parameters on another computer (running Ubuntu 14.04) it works fine. It's also fine when I run the same command but with ssh instead of autossh. So I tried strace to see if anything's wrong there. But if there is I'm not sure what it is. Any ideas?
Here's the autossh command: autossh -oStrictHostKeyChecking=no -oServerAliveInterval=15 -oServerAliveCountMax=4 -L 3130:localhost:3130 -N -i /path/to/some.pem user#remotehost
Here's the strace output (note myserver is an entry in .ssh/config that contains the same parameters as the previous command):

I had exactly the same problem with autossh 1.4e on CentOS Linux 7. autossh stopped immediately and printed the help, without even trying to connect to SSH.
The solution was to specify -M 0 on the command line:
autossh -M 0 \
-oStrictHostKeyChecking=no \
-oServerAliveInterval=15 \
-oServerAliveCountMax=4 \

Come on ... the autossh exits with
write(2, "usage: autossh [-V] [-M monitor_"..., 69usage: autossh [-V] [-M monitor_port[:echo_port]] [-f] [SSH_OPTIONS]
which means that you specified wrong arguments and it is trying to explain you how the syntax looks like. To see what is wrong, there are several things you can try:
Use -vvv switches to ssh to see more verbose log from the ssh.
Use AUTOSSH_DEBUG environment variable to get some debug logs from autossh.
I have 6 machines: 3 running RHEL 3 (Taroon Update 9) and 3 other running RHEL 5.6 (Tikanga).
They all share a NFS volume containing
an Apache 2.2.4 installation
that Apache's configuration files
the PHP scripts and other content served by that Apache
On each machine, that shared Apache is started with the "-D $hostname" option to distinguish from the Apache instances running on the other machines. (Where $hostname is the hostname of the machine).
There is a load balancer (another Apache) in front of these 6 machines, balancing the requests between them.
The problem:
I've placed a .htaccess file in a directory containing these rules:
order deny,allow
deny from all
allow from my.very.own.ip
(I've tried the same rules in the configuration file between , with the same result)
Any request from any IP other than my.very.own.ip is denied by all 6 Apaches.
Requests from my.very.own.ip that hit the first 3 Apaches (running on RHEL 3) are accepted, which is normal.
Requests from my.very.own.ip that hit the last 3 Apaches (running on RHEL 5.6) are denied (HTTP 403, client denied by server configuration), which is not normal.
I've ran a strace on all the Apache servers (and their forked children) and this is how they look like:

What do you think?
The only difference between these machines in the RHEL version. That may also mean that the NFS share ( /shark ) is mounted differently...
I've modified the .htaccess an changed the allow,deny rule with a Rewrite (requests not coming from my.very.own.ip are redirected to somewhere else). But... I'm still wondering why the same rules behave differently on different machines (same Apache, same configuration files).
Thank you!
