similar to: Timing issue with call to poll() when running asterisk -rx?

Make nbd_poll slightly more like poll(), allowing a user to detect timeouts by returning 0 on timeout and 1 when we made progress. It turns out that none of our internal uses ever expect a timeout (we only call nbd_internal_poll with timeout==-1 because we expect a reply from the server), but the public function might as well be nicer. Also handle POLLERR (server closed its read end, so our

select() has a maximum value for the FDs it can monitor, and since the libguestfs library can be used in other applications, this limit may be hit by users in case lots of FDs are opened. As solution, switch to poll(): it has a slightly better interface to check what changed and for which FD, and it does not have a limit in the value of the FDs monitored. poll() is supported on the platforms we

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

I have identical two hypervisors same operating system: Ubuntu 22.04.2 LTS Recently both virsh stopped talking to the libvirtd. Both stopped within a few days of each other. Currently if I run: virsh uri virsh version virsh list # virsh list ..nothing just hangs When I ran strace on these broken machines it get stuck at same spot: strace virsh list ...

Hi all, I have a dovecot installation which very suddenly decided to slow to a crawl yesterday after being totally fine for months. IMAP is fine, but POP3 is very painful to use, and frequently times out. here's my config: # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot_errors info_log_path: /var/log/dovecot_informational ssl_ca_file: /etc/postfix/ssl/cacert.pem ssl_cert_file:

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,

Hi! How to get usermod working with SSSD/389DS ? We have SSSD set up on our server and it uses 389DS. SSSD was enabled with the following command: authconfig --enablesssd --enablesssdauth --ldapbasedn=dc=example,dc=com --enableshadow --enablemkhomedir --enablelocauthorize --update Running for example "usermod -L username" returns: usermod: user 'username' does not exist in

I'm having trouble getting a host to join an ADS domain/realm. I have smb.conf set correctly, with the workgroup, realm, and security = ads specified. However, when I try to join with the command: net ads join -U Administrator, I simple get the message "Aborted" and it does not join the domain. If I use the -d flag to enable debugging, I see the following toward the end of the

The same application, working fine under 1.0, but after upgrade to 1.1RC1 (include edge Rails 4021) the cpu keeps spinning (took 85%) and the rest was taken by Postgresql. Looks like Rails keep sending sql statement to the database. I did a strace and following messages repeat: send(8, "Q\0\0\0\nBEGIN\0", 11, 0) = 11 rt_sigaction(SIGPIPE, {0xb7ec06bc, [], SA_RESTART}, {SIG_IGN},

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,

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

good morning everyone. I apologize if it is recurrent. But not yet found a solution. I have a problem of slowness when running "wbinfo -u" command. Analyzing the outputs of "strace" command, I noticed some timeout. After several searches, I found information that indicated remove dead domains. I do not have these domains. I performed a fresh installation. My scenario is a

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

Good afternoon. Guys, I still can not solve this problem. Some help?
