What's the kernel version on this system?<br />
I recall having strange VFS problems with older kernels (around 2.6.10).<br />
Basically, it means that any application tried to get a lock and it was granted, but before the application could do the lock, it was acquired by someone else (typical race condition).<br />
<br />
Is this directory on a NFS share or something like this?

Kernel: 2.6.9-34.ELsmp<br />
<br />
The directory is indeed on an NFS share, and is our mail server as well. &nbsp;I inherited the NFS configuration, it spans a large company and it's definitely not entirely standard and there is occasionally some wonkiness. &nbsp;I sometimes encounter locks, notably fcntl.<br />
<br />
The VSF issue has stuck me, so far.<br />

The directory is indeed on an NFS share, and is our mail server as well.  I inherited the NFS configuration, it spans a large company and it's definitely not entirely standard and there is occasionally some wonkiness.  I sometimes encounter locks, notably fcntl.

The VSF issue has stuck me, so far.

Thanks again! &nbsp;I'm sure I'll have plenty more to report, soon.

How do I re-synchronize VFS with the lock manager?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
