We have a load balanced environment with two web servers using the same cache folder on a separate file server.
Our diskcache configuration is like this:
<diskcache dir="~/imageresizercache" autoClean="true" hashModifiedDate="true" />
Any idea why we get this exception? Thanks,
Could you share the diagnostics page? /resizer.debug
It sounds like there is a bottleneck connected to the shared file server. Generally it is best to disable autoClean if the cache files are not stored locally.
