Hi all,
I have a system using smbfs that locks up every few hours.
The system is running a cron job every minute, that opens
a directory that is actually a smbfs mounted directory on a
Windows Server 2003 machine. The program reads the directory
looking for a particular file pattern, opens and processes the file
then closes and renames the file.
What this means is that the smnfs mounted directory file count
constantly
increases.
The hang mentioned is just that... the cron job doesnt run, you cannot
login on the console (well you can type root and <enter> and thats it,
no password prompt appears). If there is an open console session,
a single command can be issued then the console freezes.
The only recovery is a power cycle.
We have run the programs under a test framework to do a month load
of files in an hour, and cant hang things, yet the production box
(which is technically a better machine, but runs the same OS versions
as the testbed) will hang under 'normal' use every few hours. Its
almost
clock regular, except that it is slowly reducing the time between
hangs.
We have just purged the Windows directory, and it seems so far to
have extended the hang window.
Are there any known issues with smbfs and large directories???
NB We have other processes that use smbfs without the large number of
files on the Win systems and these have run ok for years.
It will hang on both these production versions.

Those are a lot of files =\... a temporary solution might be to
compress old log files past a particular date, or use an actual
database system, but yeah... I could see something odd occurring with
the FreeBSD machine.
However, you didn't provide a lot of information about the FBSD
machine. What are the specs for it, hardware-wise? Just curious.
Also, what's the approximate amount of files in the directory in
question?
