On-Call Playbook for Legacy Proxy (uniXXpx)

These are the campus proxy servers.

Common Failures

The squid proxy cache occasionally runs out of file descriptors. When this happens some proxy requests will fail, while others will go through. Success depends on the availability of a descriptor at that exat moment in time. This is easily resolved by restarting the squid daemon: service squid restart.

When nagios reports failure on the squid check look at /var/log/squid/cache.log for WARNING! Your cache is running out of filedescriptors.
