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

Hello, ? I need to make many (>50) ssh connections from linux to cygwin at the same time. Using Windows 2000 Server (OpenSSH_4.3p2, OpenSSL 0.9.8b and updated cygwin) and Linux RHEL4 (OpenSSH_3.9p1, OpenSSL 0.9.7a). ? It's been difficult to optimize many simultaneous connections. Here were some issues: 1.?????? On Windows XP/Professional, Microsoft intentionally cripples the TCP/IP stack.

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?

I am getting an error about to many open files. I tried to "echo 500000 > /proc/sys/fs/file-max" The number is there now, but I continue to get the error. Is there something else to do? Jerry

Hi All, Something happened on one of my 1.2.9.1 systems, SIP between * and Cisco Call Manager 4.1, leaving hung or open SIP sessions. No problem now, we found and corrected the problem. But while these hung sessions were increasing to around 480 to 500 sessions, I started getting "too many open files" on the asterisk console and sporadically could not establish new SIP connections.

Francis, I read in the list archives back that a future EventMachine release will support epoll on Linux (i.e., it''s in the trunk). Better still, is there a possibility that EM will rely on libevent so that it will be architecture independent (i.e. epoll on Linux, kqueue on FreeBSD/Mac OS X, /dev/poll on Solaris)? This is how memcached is implemented, and it would be helpful to be able

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 need to to change the ulimit to 16384(ulimit -n 16384) on boot on Centos 5.4 64 bit. How do I do that? Been searching and have yet to find a good answer. Tried to do it in rc.local but it appears to happen to late there. Matt

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

Running across some curious stuff with ulimit on CentOS 5.10. We have a non CentOS packaged version of Asterisk (using their packages) that we start at boot time with a typical RC script. Recently it started whining that it couldn't open enough file handles. As we dug further into this, it appears that at boot time, it inherits ulimit from init, which is pretty low: 1024. We've set

I'm getting "Maximum number of mail processes exceeded" messages when 512 imap Processes are active. Dovecot reports: Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1712). Either grow the limit or change login_max_processes_count and max_mail_processes settings But in my /var/service/dovecot/run script I use: #!/bin/sh mkdir /var/core chmod

Hi Johanners Berg, I put the antispam plugin to work (some days ago) and now my imap daemon dies with segfault. I don't have nothing (wrong) in logs, just a lot of segfaults...

Because of user access growth, the number of processes associated with IMAP has increased and I thought to change some of the configured parms. dovecot -n yields: # 1.1.14: /usr/local/etc/dovecot.conf # OS: AIX 1 005A928C4C00 listen: *:143 ssl_listen: *:993 disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login
