similar to: "limit -n XXX" does NOT allow on CENTOS 4.X???

Hi all, I am trying to stream for over 1k users on Ubuntu 16.04. I notice that when stream connection is over 1024, it get warning like this: WARN connection/_accept_connection accept() failed with error 24: Too many open files Tried these configs and reboot, it won't work! /etc/pam.d/common-session session required pam_limits.so /etc/sysctl.conf fs.file-max = 100000

We have CEntos 5.5 on DELL server. Due to more and more databases run on same server sometime processes number read max and cause 'resource temporary unavailable". I plan to change /etc/security/limits.conf value: oracle soft nproc 2047 ==> 4096 Do i need reboot to make it effect? How to test change is effect? Thanks.

Hello there, I’ve configured my server for maximum 50000 open files. [root at scast1 ~]# ulimit -a ... open files (-n) 50000 ... max user processes (-u) 65535 While im doing the Load Test 1, my server only reaches ~1015 listeners. I’ve set this on etc/security/limits.conf : icecast hard nofile 50000 icecast soft nofile 60000 icecast soft nproc 65535 icecast

We have some ORACLE PGA problem and ORACLE document say we can serup lockmem(Max lock memory) to higher value. $ulimit -a time(cpu-seconds) unlimited file(blocks) unlimited coredump(blocks) 0 data(kbytes) unlimited stack(kbytes) 10240 lockedmem(kbytes) 3145728 memory(kbytes) unlimited nofiles(descriptors) 65536 processes 2047 Can anyone tell me how to set lockedmem to higher value on

It all looks like a workarounds. I would suggest using a proper solution, such as systemd, that is present in ubuntu 16.04 by default, and where you can raise system limits per system service just by tweaking its config file. m.

I posted a few days back asking about configuration issues with a modestly large number of IMAP connections. Several people were kind enough to respond with various ideas. Armed with those ideas and Google, I was able to determine the underlying configuration issues with CentOS 7 and Dovecot 2.2.10. I did some further benchmarking to ensure that we could properly plan our server

I'm running fedora directory server on some boxes in a multi-master arrangement. The problem is that when dirsrv is lauched from init (on boot) the maximum number of allowed file descriptors (ulimit -n) is only 4096. That means that the slapd process can only accept ~4k connections, and it needs to accept ~10k or so. The value for nofile for all users in /etc/security/limits.conf (and

When restarting Dovecot 2.2.10 (via atrpms) on RHEL 6, I get the error: Warning: fd limit (ulimit -n) is lower than required under max. load (1024 < 4096), because of default_client_limit # doveconf default_internal_user default_internal_user = dovecot Should dovecot print this warning based on $default_internal_user, or based on root? As root: # ulimit -n 1024 As user dovecot: $ ulimit -n

I am using CALDERA OPENLINUX 3.1.1 with latest patches and Samba 2.2.5 on it. But recently I start to receive linux error "kernel: VFS MAX FILES REACHED" and Samba error "Too many open files". After it I tuning linux increase open files descriptors in /etc/security/limits.conf * soft nproc 4094 * hard nproc 16384 * soft

We recently switched over mail servers to one running dovecot and postfix on RedHat Enterprise 6. The mail store is NFS on a NetApp filer, the index files are on local disk. We have about 6000 total active users, though not all of them access the system at the same time. All goes well for a while, then we start seeing errors like this in the log: dovecot: imap-login: Error:

We are tried to count how many files belong to certain group. Our system administrator told us "non-owner" can easy change file group name to another. I have been tried several combination and never successful (only ROOT can change file group to other name). Does anyone know how "no-owner" can change file group name? Thanks.

Why can't non-uid 0 users have more than 1024 file descriptors when logging in via ssh? I'm trying to allow a user to have a hard limit of 8192 file descriptors(system defaults to 1024) via the following setting in /etc/security/limits.conf: jdoe hard nofile 8192 But when jdoe logs in via ssh and does 'ulimit -Hn' he gets '1024' as a response. If he tries to

I just setup CENTOS 4.7 with latest patches on DELL server. I also configured NTP point to out time server.

Hi! Question from the novice. I have to permanently increase number of opened files ( ulimit -n 16384 and ulimit -Hn 16384) for some application. I did custom kernel based on https://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/sysadmin-guide/s1-custom-kernel-modularized.html and application documentation ( written for RH 9), no error during all makes but I have panic during the

Hi Louis, Thanks for information, find it sometimes is a real challenge. Would you please share your how to link? I wish to read it. For the .local domain I suppose I have nothing to do. This is a running windows Active Directory and it is not possible to change domain suffix. Here is my /etc/hosts 127.0.0.1 localhost.localdomain localhost 10.254.104.8 wdc04.aa.local wdc04 10.254.105.208
