Problems when using multiple sites from one codebase

The default site works fine just as it's supposed to, but my second site shows this in the logs:

"unlink(/tmp/browscap.csv): No such file or directory in /var/www/localhost/htdocs/modules/browscap/browscap.module on line 193."

It however *does* import the browscap file and load the database with the correct information.

My third site however... Doesn't appear to do anything at all? The cron jobs show in the logs, but it doesn't import anything or even try to. Both the other sites import on the same cron job which show in the logs:

"New version of browscap imported: 2005-08-28 17:42:40 UTC"

Obviously identical... Other than the error message I said about above for the second site.

The only thing I can think of that is 'upsetting' it could be that all my crons are scheduled to run together on the hour, every hour. Therefore I can understand maybe the error from the second site as maybe the first sites cron deleted it before the second could access it - but the third one not doing anything at all is puzzling? Especially as it seems to have updated the 'timestamp' in settings/browscap - just added nothing to the database or written anything to the log.

If this is simply a case of "you shouldn't run all your crons together at the same time" maybe someone should add this to the README file? Else, hopefully something could be done to the code to avoid multiple sites conflicting over the same files? Maybe instead of naming the temporary file browscap.csv or whatever it's called, it could be named after the sites name? Then it'd be individual to *that* site and would be no conflict? Just a thought...
