Could anyone help with this cache problem ...
I seem to get these errors creep into existence for certain static document
(e. g. images).
Everything is fine for a couple of days, then I start getting cache errors
on access to some static files.
Once a certain URI starts failing, it keeps failing, then gradually others
join in.
To restore access to them, I have to stop tomcat, delete the work directory
(which includes the cache of course!) and restart tomcat.
Then everything is fine for a couple of days again.
I've checked the recommendations for heapsize and freememory as far as I
understand them.
I've done a search of the mailing list, but have not managed to find
anything specific to this error.
System is Windows 2000 IIS5 using ISAPI to tomcat 4.0.1 to cocoon 2.0.1
jdk1.3.1
Here's the error I get.
(By the way, /main/ is the name of my cocoon context and directory)
