Dear all,
The setup - iFolder 3.6 running on OES2 Linux with default store on NSS volume on the SAN.
Lately, it has been crashing often with the following message in the logs (attached)

The event context cookie has expired --> Too many open files

I am able to stop apache and restart after cleaning up the temp files/mono processes. But it crashes again after few hours.

The simias data store is about 644.7MB with 2123 files and 302 sub-folders

Can anybody give me an idea what could be causing this?
