I used to work with an HP-UX system and the old admin told me there is an upper limit on the number of zombie processes you can have on the system, I believe 1024.
Is this a hard fact ceiling?
Hi,
I have a file which has some 50 hosts, I want to login to each host using ssh and execute any command. I am using fork function in perl. I am able to login to each host and execute the command in the hosts paralelly, but it spawing/forking 50 processes at a time.
It will consume the cpu utilization if so many processes open at a time.
I'm looking for a way to limit a processes disk io to a set speed limit. Ideally the program would work similar to this:
$ limitio --pid 32423 --write-limit 1M
Limiting process 32423 to 1 megabyte per second hard drive writing speed.
I am consistently running out of inotify resources, leading to errors along the lines of:
# tail -f /some/files
tail: inotify resources exhausted
tail: inotify cannot be used, reverting to polling
This eventually happens even if I grow the value of fs.inotify.max_user_watches.
Hi Experts,
I am executing multiple instances(in parallel) of perl script on HP-UX box.
OS is allocating substantial amount of CPU to these perl processes,resulting higher cpu utilization.
Glance always shows perl processes are occupying majority of the CPU resource.
I run YouTrack on a small server. By default it launches a lot of processes that take all available memory.
Manipulations with Java parameters don't help, so as I see, the only way to reduce memory usage is to limit the number of processes. Is there a way to do that?
Dear All,
I am new to this community and this is my first post. I am facing an issue where the process starts hanging. When I closely look at the logs I come to know that some of the child processes that are forked by the parent process are not finished. Regarding this I have a few questions:
I'm tuning the nofile value in /etc/security/limits.conf for my oracle user and I have a question about its behavior: does nofile limit the total number of files the user can have open for all of its processes or does it limit the total number of files the user can have open for each of its processes?
Specifically, for the following usage:
oracle hard nofile
In a short question: If 10 requests hit Apache, does it process them one by one, so when R3 finishes, then it starts to run R4, or does it fire 10 processes/threads/whatever and are resolved simultaneously?
Now some background: I have a PHP script that takes up to two minutes to do some processes.
