ulimit

I have a node.js process that needs to read from multiple named pipes fed by different other processes as an IPC method. I realized after opening and creating read streams from more than four fifos, that fs seems to no longer be able to open fifos and just hangs there. It seems that this number is a bit low, considering that it is possible to open thousands of files concurrently without trouble (for instance by replacing mkfifo by touch in the following script). I tested with node.js v10.1.0 on MacOS 10.13 and with node.js v8.9.3 on Ubuntu 16.04 with the same result. The faulty script And a

I am using supervisord to start my java app. The application is working OK, but my ulimit nofiles is not set. I could do it in one machine, using debian. but there is a problem on the second machine that this configuration is not working. Basically, I start my app with a script: #!/bin/sh iscsiJar="/mnt/cache/jscsi/udrive.jar" ulimit -SHn 32768 # função para iniciar a aplicação java -XX:MaxHeapFreeRatio=70 -Xmx2048M -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=dump.hprof -jar $iscsiJar But my command cat /proc/4171/limits keeps saying: Max open files 4096 4096 files Any hint? I already

I am trying to run Jest tests, but I'm getting the following error: Error reading file: /Users/mike/dev/react/TestTest/node_modules/react-native/node_modules/yeoman-environment/node_modules/globby/node_modules/glob/node_modules/path-is-absolute/package.json /Users/mike/dev/react/TestTest/node_modules/jest-cli/node_modules/node-haste/lib/loader/ResourceLoader.js:88 throw err; ^ Error: EMFILE: too many open files, open '/Users/mike/dev/react/TestTest/node_modules/react-native/node_modules/yeoman-environment/node_modules/globby/node_modules/glob/node_modules/path-is-absolute/package.json' at

I'm trying to use the spread() function from the tidyr package in R on a dataframe that has about three million observations. It's returning the following error message: Error : C stack usage 26498106 is too close to the limit When I run Cstack_info() , it tells me > Cstack_info() size current direction eval_depth 7969177 15272 1 2 Following the advice in the answer to this question, I've tried increasing the stack size by running ulimit -s 32768 in a terminal window and opening Rstudio from the terminal. When I try this, however, the output of Cstack_info() is unchanged, and when I run my

I am modifying /etc/security/limits.conf on the machine, and then installing Supervisor in a Chef recipe. After the recipe run finishes, if I run cat /proc/<process id>/limits I see: Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max open files 1024 4096 files If I log into the machine and run service supervisor restart , the max open files is then set correctly. However, if I run this command in the recipe (right after installing supervisor, at the very end of the recipe, anything) the limit does not change. It is not until I log in and manually run that command
