Bug Fix Advisory
An updated squid package that fixes various bugs is now available.
Squid is a high-performance proxy caching server for Web clients,
supporting FTP, gopher, and HTTP data objects.
An updated squid package that fixes various bugs is now available. Bugs
fixed in this updated package include:
- the init script for squid would always return the error code 0 (the
process is running as expected). The init script is now compliant with
Linux Standard Base (LSB) guidelines, which resolves this issue.
- if the refresh_stale_hit feature was enabled, the following warning was
returned in cache.log:
STALE: Entry's timestamp greater than check time. Clock going backwards?
In this updated package, this issue has been resolved.
- on machines running squid and setup without a Fully-Qualified Domain Name
(FQDN), running the command "service squid status" (which caused squid to
run the "squid -k check" command) caused squid to crash, returning the
FATAL: Could not determine fully qualified hostname. Please set
With this update squid no longer aborts in this circumstance.
- the owner of the "/usr/local/squid" directory was not the squid system
account. In this update, when squid is installed, the owner of this
directory is now correctly set to the squid system account.
- squid's internal Domain Name System (DNS) system may have corrupted
cached search queries if multiple DNS search paths were defined in
"/etc/resolv.conf". Consequently, squid would crash with signal 6, write a
core dump, and restart. In this update, squid now correctly stores these
queries, which resolves this issue.
- using the squid_unix_group parameter in "/etc/squid/squid.conf" may have
caused squid to crash, resulting in the following message being returned to
(squid): The unix_group helpers are crashing too rapidly, need help!
With this update, squid no longer crashes in this circumstance.
All users of squid should upgrade to this updated package, which resolves
