Thanks for answer. I am very sad to see that. I had examined samba behavior with tracer and had seen too many poll, fcntl and stat system calls by samba task[ldapsrv] process Elapsed Times for PID 1423, SYSCALL TIME (ns) dup 2653 flock 5811 lseek 33513 geteuid 42747

it's verry slow i saw in the archives something about strace and will include it below please help: my dovecot is crawling when downloading through pop here is my last trace file contents :18:04.657706 poll([{fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=15, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=13, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=17,

Hi, I installed Dovecot on FreeBSD 4-STABLE machine and have a problem. MTA is postfix delivering to ~/Maildir, runs perfectly. Dovecot is configured to use plaintext auth, config file is at the end of this mail. When trying to get mail via IMAP, I'm getting the following errors: /var/log/dovecot.log > Aug 24 12:00:35 Info: Dovecot starting up > Aug 24 12:00:51 Info: Login: goshik

All, [version: dovecot-0.99.11-4.EL4.src.rpm] We recently experienced an issue that prevented all new IMAP logins from occurring. Although it appears that it was due to running out of available system file descriptors, I'm still not sure what the true root cause was as I can't replicate the same error in our test environment. The system file descriptor max was set at (per `cat

Hello everybody! We have a cluster of servers managed by VMmanager 5 KVM (by ispsystem). A typical node: # cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) # uname -r 3.10.0-693.11.6.el7.x86_64 # rpm -qa |grep libvirt libvirt-daemon-driver-qemu-3.7.0-1.el7.centos.x86_64 libvirt-daemon-driver-storage-disk-3.7.0-1.el7.centos.x86_64 libvirt-3.7.0-1.el7.centos.x86_64

Hi! Occasionally of late, I've seen a few cases where libvirtd cpu usage shoots up to 100% and stays there indefinitely. This seems to happen when a QEMU VM is starting up, although on one occasion I *think* I saw it happen after a QEMU VM was p2p-migrated. Doing strace -f -p <libvirtd pid> reveals a flood of poll() functions calls like these: [pid 1690] poll([{fd=3,

The latest version that Western Digital has shipped with the My cloud devices accesses the disk about twice a minute. The access to /dev/sda2 is causing the system to keep the disk from going into standby mode. I don't understand the call to quotactl every minute when no one is trying to access the share. An strace of one of the processes shows the following: poll([{fd=13,

Good day oh technical ones . I was running Samba 4 (client only, not using it as a DC so effectively running Samba 3 code from the Samba 4 tree) and, other than a little "Gotcha!" regarding decoding Kerberos PACs, it was all working perfectly. Then recently I had to upgrade, to "4.2.0pre1-GIT-b505111" (I had to upgrade the OS on the server

Hi I have upgraded from samba 3.6.19 to samba 4.0.13 on Debian Wheezy 64-bit with Samba 4.0.13 from wheezy-backports. I use winbind to authenticate against a two-server AD domain on Server 2012 functional level and forced LDAPS. After upgrading from 3.6.19 to 4.0.13 everything still works for me as usual. That is samba shares authentication, all things relying on the keytab, SSO logins with SSH

hi ! i have succesfully compiled libshout/icecast/ices on a quad ss20 (4xhypersparc@125mhz, 128mb ram). ten out of ten for a robust, cross-platform build, guys ! it compiled straight out of the box. i can start the server and it even connects to a remote server and starts to relay. when i run xmms from another machine and connect, it stops at "pre-buffering 0/32k". here's an

Hi, My laptop runs a local IMAP server so that I'm immune from breaking my mail client, and when playing around with powertop I discovered that Dovecot (in particular imap-login) wakes up every 1000ms and then every 50ms even when no clients are connected. A bit of stracing shows this: gettimeofday({1180875699, 667917}, NULL) = 0 <0.000010> poll([{fd=7,

Hello, I've got an issue with RHEL6 running smbd & winbindd version 3.6.9-168.el6_5. This is authenticating against a Windows 2008R2 domain using the rid backend. If I run any command that has to look up user info I get a 35 second delay, after this initial delay it's fine until the cache time-out, then it happens again. This is making logins and most commands hang for 35 seconds

Hi, my environment: Win2003 AD + Samba4 as second RW DC on debian wheeze. Samba compiled from source: samba --version Version 4.1.0pre1-GIT-c932b13 Installed Samba4 according these: https://wiki.samba.org/index.php/Main_Page https://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC https://wiki.samba.org/index.php/Samba4/Winbind Everything went good according tutorial, until I try get

nmbd has been dying on me occasionally. I'm running mandrake 9.2 with samba3-server-3.0.0-2mdk. We've got our users in ldap but I'd seen this symptom previously when I was using an earlier version of samba that didn't support ldap. There is nothing useful in the logs and a PS shows a nmb process still running. This last time around, I had a ptrace running on both nmbd

This is a continuation of a discussion we were having on IRC. The problems with IRC are it's not recorded and it's hard to have deep technical conversations. I hope this is a decent summary. Problem simply stated: Certain NBD servers (qemu-nbd in particular) are able to simultaneously read and write on a socket. ie. They can be simultaneously reading a request and writing the reply to

Hi all, I'm pulling my hair out on this problem and wanted to throw it out there to see if anyone else had run across it. I recently restarted my server. There were some network config issues that caused the interfaces not to come back up, but my colo company got those resolved. However, after restart, my IMAPS server has stopped responding to outside requests. I can successfully access
