Also check that your IOSP is calling raf.close()  in its close statement.

Is "<NetcdfFileCache> maxFiles from 400 to 20" correct ??

New Ticket: HTTP file cache problem?

We're accessing files through TDS using a script (to access with our IOSP stuff) and after reading numerous files (which was made possible by changing <NetcdfFileCache> maxFiles from 400 to 20) we are encountering a new problem that seems to be unrelated to HTTPFileCache (because it happens well past the 40 file limit). Can you help?
