![]() I'm really not interested in Mendeley given that it's proprietary software, and really the only proprietary stuff I'll use is games or firmware/gpu binary blobs.ĭocear looks like it should be the most useful to me, based on this: īut when I open up Docear, it comes up with weird mind-mapping charts, and wants me to create projects etc. relevant to my research, subcategorised by topic.įor BibTeX, I usually generate these more or less by hand using ebib in Emacs.ĭo people with vaguely simliar needs find Docear, Mendeley, or Zotero useful? I'm mainly interested in better organising my PDF collection and better handling of BibTeX entries.Įssentially my current PDF setup is that I have a folder where I keep PDF versions of articles, books, etc. Today we’ve seen how to use memory limits to prevent Docker container memory overhead.I'm interested in determining whether any of Docear, Mendeley, Zotero would actually be useful in my workflow. We’re online 24/7 and can attend your request in a few minutes.Ĭontainers crashing due to “Out of memory” errors is a common issue in Docker servers. If you are not sure how to fix the memory issues in your Docker host, click here to talk to our Docker experts. Many times, we’ve reduced memory usage just by choosing a lean OS like Alpine Linux and building a custom Docker image. Similarly, we’ve seen developers use bulky images (eg. This often leads to frequent website crashes in containers with very low memory limits. We’ve seen Docker users set arbitrary memory limits based on how big their database is. ![]() VIRTUAL_HOST:, A quick restart of the container will limit the memory to the set value. Once we know the safe memory limit for each container, we modify the Docker Compose files with the setting mem_limit like so: container_name: We filter out the the outlier values (solitary spikes), and determine what’s the memory value where the site remains functional 99.9% of the time. The memory values are written into a file, and the 99 percentile value is calculated after 1 week.Ī good sample period if 1 week, where we take into account traffic patterns of businesses through all weekdays, work hours and week ends. ![]() Now, the question is how do you find out the normal usage boundary for a container?įor that we use the statistics function of Docker, and chart the memory usage over a period of 1 week. Here at Bobcares, we help our customers prevent Docker crashes by setting up memory limits.īy assigning a limit to each container, we limit the damage due to traffic spike or resource abuse to just one website. When the Docker host runs out of memory, it’ll kill the largest memory consumer (usually the MySQL process), which results in websites going offline. When the traffic in one container increases, it’ll grab more memory from the Docker host to run its processes. What causes Docker container memory overhead?īy default, docker does not impose a limit on the memory used by containers. Jan 31 15:58:03 dockerhost1 kernel: oom_reaper: reaped process 24707 (mysqld), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB Here’s a typical error log: Jan 31 15:58:03 dockerhost1 kernel: Out of memory: Kill process 24707 (mysqld) score 19 or sacrifice child Here at, we help web developers and digital marketers to setup and maintain Docker based web hosting servers.Īnd a common issue we resolve is containers crashing due to “Out of memory” errors as a result of traffic spikes, spam attacks, etc. Many developers now use Docker to host their apps in production servers.īut Docker in production servers often cause resource bottlenecks – especially Docker container memory overhead.
