When I run next build in my server, it gets stuck here, and the website also crashes and turns into a 504 Gateway Timeout error:
info - Loaded env from /home/ubuntu/MYPROJECT/.env
info - Using webpack 4. Reason: future.webpack5 option not enabled https://nextjs.org/docs/messages/webpack5
info - Checking validity of types
info - Using external babel configuration from /home/ubuntu/MYPROJECT/.babelrc
info - Creating an optimized production build..
This does not happen all the time, maybe 1 time every 5 to 10 deployments.
I then have to stop and start the EC2 instance. Right after the build command always runs very quick. Which could mean I have memory issues in the server? How could I resolve this?
I have a t2.micro instance with 8GB of storage.
Usage of /: 76.2% of 7.69GB
Memory usage: 50%
Could be that upgrading resolves this issue?
I am trying to set up a development environment for Apache/AirFlow on MacBook with macOS 10.14.x.
I have installed docker, virtualbox and created virtual machine and created containers with web_server, worker, scheduler and redis, postgres.
I run :
docker-compose up -d
But, when I visited http://localhost:8080, I got:
This page isn’t working
localhost didn’t send any data.
ERR_EMPTY_RESPONSE
In the docker-compose log file, I found:
[mwebserver_1 [INFO] Parent changed, shutting down: <Worker 34>
[mwebserver_1 [INFO] Worker exiting (pid: 34)
[mwebserver_1 {{cli.py:815}} ERROR - No response from gunicorn master within 120 seconds
[mwebserver_1 {{cli.py:816}} ERROR - Shutting down webserver
I am not sure what the problem could be.
Any suggestions would be appreciated.
After start the docker container's.
Try to run docker exec -it NAME_OF_CONTAINER /bin/bash. After that you're gonna into container bash and you can run airflow webserver.
Bamboo-jmeter task: Should time gap there before starting the jmeter master/slave. We have created bamboo task (SSH task1-with slave host, SSHtask2-with 2nd slave host, SSH task3-with master host and run commands). When first time the the task getting an error remote engine is not able to configured whereas able to telnet the hosts, also jmeter-server is already started.
However when disable SSHtask1 and task2 for the 2nd time run, it is able to run successfully and getting results also.
Should jmeter master start after 1/2 minutes of server started? Please suggest
Able to overcome the problem by adding sleep time of 120 seconds after running the jmeter-server before starting the jmeter master.
I'm using Vagrant and Ansible to create my Bitbucket Server on Ubuntu 15.10. I have the server setup complete and working but I have to manually run the start-webapp.sh script to start the server each time I reprovision the server.
I have the following task in my Bitbucket role in Ansible and when I increase the verbosity I can see that I get a positive response from the server saying it will be running at http://localhost/ but when I go to the URL the server isn't on. If I then SSH in to the server and run the script myself, getting the exact same response after running the script I can see the startup webpage.
- name: Start the Bitbucket Server
become: yes
shell: /bitbucket-server/atlassian-bitbucket-4.7.1/bin/start-webapp.sh
Any advice would be great on how to fix this.
Thanks,
Sam
Probably better to change that to an init script and use the service module to start it. For example, see this role for installing bitbucket...
Otherwise, you're subject to HUP and other issues from running processes under an ephemeral session.
i have done an hadoop cluster installation with cloudera manager. After this installation impala status has become bad.
I have the following error for master node:
Web Server Status
and this one for nodes with imapala daemon:
Impala Daemon Ready Check, Web Server Status
looking into logs i have found some errors:
The health test result for IMPALAD_WEB_METRIC_COLLECTION has become bad: The Cloudera Manager Agent got an unexpected response from this role's web server.
looking into cloudera-scm-agent.log there are those errors:
1261 Monitor-HostMonitor throttling_logger ERROR (29 skipped) Failed to collect NTP metrics
i tryed to install NTP (sudo apt-get install ntp) but after this installation HDFS, HIVE, YARN and others services goes bad, removing that only impala goes bad.
MainThread agent ERROR Failed to connect to previous supervisor.
Another error is this:
Monitor-GenericMonitor throttling_logger ERROR Error fetching metrics at 'http://nodo-1:50075/jmx'
i tried looking all hostnames and seems correct...
so, what is this problem? how can i solve it?
I also had problem with NTP, the problem still existed after installing NTP , but when I done sudo service ntp restart the error was fixed
