Description:
We're down. Web OPAC error message: Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
GUI message: Communuication error (global-7) Failed to read reply

I cannot connect via SSH either.

Resolution:
It seems Oracle went down unexpectedly. Site was able to restart Oracle.

I see this message in the Oracle alert_log:

Linux-x86_64 Error: 23: Too many open files in system

This message is discussed in KB's 16384-28193 and 16384-31297. I suggest that you check the parameters described there and adjust them as appropriate.
