## Symptoms

- * ICAP server stops accepting files from ICAP client.
* Restarting PHP and ICAP processes solves the issue temporarily.
* "ATTENTION!!!! Not enough available servers" error message is shown in *$FWDIR/log/c-icap/server.log*

## Cause

**Background:** Internet Content Adaptation Protocol (ICAP) server functionality can be added to Check Point Security Gateway R77.30 running on Gaia OS. This functionality would enable Check Point Security Gateway to respond to an ICAP client's modification queries, and consult the Threat Emulation blade to help an ICAP client decide whether a file is malicious or not.

Cause: Too many connections are opened from the ICAP client to the ICAP server. This exceeds the configured number of connections on the server.
