Hi! A bit late, but was out of office a few days...

I do not see any error messages in log files... Any idea? I think you have to distinguish two things: file handles and open files (file descriptors). The difference between file handles and open files is, that a process can have more open files than file handles. That’s because things like current working directories, memory mapped library files and executable text files (i.e. the program itself) are counted as open files but don't use file handles. On the other hand file handles rarely get unallocated, they rather get unused and are reused by some new process. As far as I understood, the difference is that a file handle is part of an additional layer of the C standard I/O library routines. See more on file handles and file descriptors in <<http://en.wikipedia.org/wiki/File_descriptor>>. Concerning the file handle problem: /proc/sys/fs/file-nr shows a statistic of file handles in three values: First value is the number of allocated file handles, second the number of free allocated(!) file handles (with Kernel 2.6 always 0) and the third number is the system wide maximum of allocatable file handles. The maximum is configured in /etc/sysctl.conf by "fs.file-max" and can be controlled via sysctl (man 8 sysctl) or via /proc/sys/fs/file-max. Concerning "too many open files" you might have a problem with the maximum number of allowed open files per user. Look at "lsof -u <user> | wc -l" to see how many open files all processes of <user> have. Look at "ulimit -n", which shows the number of allowed open files for the user. Only root can increase the limits (ok, the user can do this between hard and soft), so for a user different from root you have to configure this in /etc/security/limits.conf. See the bash manpage for the builtin "ulimit". Hope this sheds some light on your problem...
