All,
My MRTG of Squid (2.5S14) sometimes showing the "Storage Mem Size" (and
"Total Memory" as well) went down then up by itself. I did not any error
message cache.log at the time of symptom happen.
Yesterday, I applied the patch of Squid 2.3S14 but Squid is dying (when
loaded by rc.local) with error "FATAL: Received Segment Violation...dying".
However, I cannot create stack trace as I don't know how to do. After
un-patching, Squid can be loaded from rc.local.
Thx & Rgds,
Awie
