Chromium: pthread_create error: Resource temporarily unavailable An example of the pthread create bug on another program is here https://my.vertica.com/docs/5.0/HTML/Master/16468.htm. Some other side-effect messages appeared like: [16751:16780:0408/145921:ERROR:shared_memory_posix.cc(225)] Creating shared memory in /dev/shm/.com.google.Chrome.z77EvR failed: Too many open files [16751:16780:0408/145921:ERROR:host_shared_bitmap_manager.cc(122)] Cannot create shared memory buffer The FIX I have all kinds of browsers installed on my computer, and I'm always messing around with their configurations. I'm working on some stuff that requires using different browsers. I resource temporarily unavailable eagain also have a lot of open tabs. But this bug appeared whenever I was running Chromium and Google Chrome, making me believe they couldn't be run together. The problem is that with a decent number of tabs both browser start hundreds of threads. Like 500! Here's some commands to count running threads on your system. Not sure which one is best, they give different answers: #Count all threads ps -elfT | wc -l ps -eLf | wc -l #Count threads, shows more, don't know why ps -eLo pid,cmd,nlwp | wc -l ps axms #Count threads for different browsers ps -elfT | grep firefox | wc -l ps -elfT | grep chrome | wc -l ps -elfT | grep chromium | wc -l ps -elfT | grep opera | wc -l If you do the test you'll see that chromium and chrome use huge amounts of threads. Right now I have Chrome@658 threads, Chromium@601 threads, Firefox@39 threads, Opera@4 threads. But why is there a limit anyway? Threads are cheap and I have lots of RAM. And, what is the limit set at? To find out, we'll use the ulimit command. #Check max number of threads: $ ulimit -u 1024 #Check limits for all ressources: $ ulimit -a ... Who the heck came up with 1024 and why? Accordin

It simply creates threads that die straight away. What I have found is that after 93 to 98 (it varies slightly) successful calls, every next call to pthread_create() fails with error 11: Resource temporarily unavailable. I think I'm closing the thread http://stackoverflow.com/questions/12843890/98th-call-to-pthread-create-fails correctly so it should give up on any resources it has but some resources become unavailable. The first parameter of the program allows me to set the interval between calls to pthread_create() but testing with different values, I've learned that the interval does not matter (well, I'll get the error earlier): the number of successful calls will be the same. The second parameter of the program allows me to set a sleep interval after a failed call but the length of the interval does not seem to make any difference. Which ceiling am I hitting here? EDIT: found the error in doSomething(): change lock to unlock and the program runs fine. The question remains: what resource is depleted with the error uncorrected? #include

I believe docker is either hanging or crashing as soon as number of containers are reaching more than 500. When I debug /var/log/messages I found that its giving resource unavailability issue on the same machine where I used to create around 1200 containers successfully. When I studied I found that there has been an introduction of TasksMax flag which sets number of threads to 512 by default but this flag is not supported by CentOS 7 or any OS versions running 3.10.xxx and giving following error: [/etc/systemd/system.conf:58] Unknown lvalue 'TasksMax' in section 'Manager' Kindly suggest a way forward because it completed stopped our operation and we are not able to proceed with a high number of containers. I tried to remove TasksMax from docker.service file still there is no success.
