1.0alpha3: fcntl() complaints?
Hi, Since installing 1.0alpha3 this morning, I've seen this syslog complaint a few times. Anything to worry about? A "server too busy" issue? imap(user): fcntl() failed with mbox file /var/mail/user: Resource temporarily unavailable Jeff Earickson Colby College

Bug? 1.0.0-test28 NFS locking problems
Hi Slight problem - linux 2.4 running dovecot, Solaris 2.8 home directory server. Full lockd support etc. I had to make the following code patches (at end of mail for clarity) to get dovecot to read the users mbox files at all. 1) fcntl with F_SETLKW will not work against a Solaris 2.8 server as proved with a small test program. Other forms of fcntl (ie F_SETLK) are OK. I noticed there are

Why portmap is needed for NFSv4 in CentOS6
Hi all, I have setup a CentOS6.3 x86_64 host to act as a nfs server. According to RHEL6 docs, portmap is not needed when you use NFSv4, but in my host I need to start rpcbind service to make NFSv4 works. My /etc/sysconfig/nfs # # Define which protocol versions mountd # will advertise. The values are "no" or "yes" # with yes being the default MOUNTD_NFS_V2="no"

Full MVCC in Brass
I'm one of the developers of Notmuch, an email client that makes extensive use of Xapian. For some time, full multi-version concurrency control (MVCC) has been on our wish list. Olly mentioned that brass now uses free lists---a key step toward full MVCC---and I offered to pitch in on putting the other pieces into place. Before I wade too deep into this, I wanted to propose my plan. Full

Newbie: unable to access mailbox more than once
Hello, I'm using dovecot as a mail relay so that I can back up my providers IMAP mail locally. I'm impressed how easy this was to set up, but I'm having a quirk that I would like help with, if possible. There are many weak links in my set-up chain, if you will, but I think I've narrowed the problem. I'll describe my set-up anyway. I'm running dovecot 1.1.4 on ubuntu

NFSv4 on CentOS 5.5
Hi, What is the magic juju that I have to put in /etc/sysconfig/autofs to get autofs to default to using NFSv4, rather than NFSv3, for mounting file systems? I don't want to place these flags into the automount maps themselves because we have a varied network with Sun, CentOS, RedHat and Macintosh systems, and the flags that have to get added to automount maps (which we distribute centrally

Database left unlocked by Tcl bindings
I discovered, while trying to set up Tcl bindings for Notmuch (https://notmuchmail.org/), which uses Xapian, that flintlock was not being locked (I had lost updates). I then found that opening a Xapian database for writing directly via the Xapian Tcl bindings also silently fails to lock flintlock. I have taken a copy of flint_lock.cc to play with, and I find that it locks the file when called

Samba daemons hang trying to lock locking.tdb
Hi, A day or so after starting samba, some daemons (diferent forks) begin to hang. Then, the WinXP clients hang too completely. When I try to figure out what is happen, I see that smbd daemons hangs always in a fcntl64() call: # strace -p 6414 Process 6414 attached - interrupt to quit fcntl64(14, F_SETLKW64, {type=F_WRLCK, whence=SEEK_SET, start=3684, len=1} <unfinished ...> Process 6414

Permission denied when running from xinetd
Hey folks, When I run rsyncd from xinetd and try to rsync I will get permission denied error: rsync: chdir /home/test failed : Permission denied (13) If I shutdown xinetd and start standalone daemon ( rsync --daemon --config /etc/rsyncd.conf) everything works as expected.

MIT Kerberos suddenly stopping
Hello, I'm using samba 4.7.3 to run an AD and I'm currently having issues with the MIT kerberos because it stops some time after starting (and apparently working correctly) without logging nothing out of the ordinary. My setup has 2 DC: one in an ubuntu 12.04 with version 4.1.9 (which we're migrating from) and the one I mentioned in CentOS 7 (which will be the only DC in the future).

Help with NFSV4 server
Hi Everyone, I have been trying to setup an NFS v4 File Server but have come across an odd issue. Mounting the /nfs4exports/share appears to be successful and the information displayed about partition size and free space seem correct but if I try to do anything inside the mounted directory the client will just hang. Does anyone have any idea what I am missing?? I have try disabling all

3.6.10 file handle leak under ancient 32-bit kernel
Hello, I've come across a curious issue with Samba 3.6.10. When running 'emacs' version GNU Emacs 23.3.1 (i386-mingw-nt6.0.6002) of 2011-03-10 on 3249CTO on Windows Server 2008 SP2 x64 and issuing a file "revert" of one sort or another against a Samba-served file, the 'smbd' process leaks two or three handles. Eventually, when 16k handles are open, this causes

nfs locking between current and stable
Hello, I am attempting to get flock/file locking working between my -stable (updated ~19 may) nfs file server and -current desktop; the server is running lockd/statd, and both my mail client (mutt) and a simple perl program complain that files on the nfs server cannot be locked. I am aware that there has been work on the nfs locking code in current, and have a vague recollection of a workaround

Dovecot lock problem
Hi, We have a few users experiencing locking problem. When starting Thunderbird, there is no new emails in Inbox. Dovecot createa a lock file /var/spool/mail/<user>.lock. It never completes openning Inbox. If closing the mail client, the open imap session does not get closed, nor the lock file get deleted. Here are the errors in log: dovecot: Oct 13 11:18:35 Warning: IMAP(user1): Our

I run a Gentoo linux in this hardware and I am facing an out of signal screen just after the boot (when the nouveau module is loaded). If I blacklist this module and modprobe it in the prompt, the screen gets out of signal in my 1080p TV in this moment. I tried recompile the kernel enabling and disabling a

smbd high cpu load
We have a Linux file server for a set of computer science and engineering labs where each lab contains machines running Mac OS X, Ubuntu Linux, or some incarnation of Windows. At times the these machines become almost unusable and I think I have narrowed the problem to smbd processes soaking up all the CPU on the server. Running 'top' on the server reveals a dozen or so entries like
