Dear Jeremy,

Sharity is not configured (by default) for immediate propagation of changes
made on the server. That's for performance reasons and because this feature
is rarely needed. Furthermore, even Windows NT is very buggy in reporting
file sizes of open files. Depending on factors we have not been able to
isolate, it may report old (too short) file sizes on open files.
If you want to turn of Sharity's caches, please change the following
configuration settings in the file /usr/local/sharity/etc/sharity.cfg:
attributesCacheTime = 100; (or as short as you want)
dataCacheTimeNoLock = 100; (or as short as you want)
closeDelayBatchLock = 100; (or as short as you want)
closeDelayExclusiveLock = 100; (or as short as you want)
closeDelayNoLock = 100; (or as short as you want)
If this fixes your problem, you can experiment with the settings to get a
compromise beteween performance and consistency. If you need more help, I can
dig out an e-mail exchange we had with a customer who wanted to do the same
thing as you...

If this can't be achieved with a configuration change to Sharity, please
tell me. I'd then be interested to see what Dave makes different from
Sharity.
Regards, Christian.
