I've searched the archives and looked in the definitive guide but can't find any solutions to SO_Fail -1 for all image files I see in my store.log file. I know that this means squid could not save the object to disk. I'm trying to just cache images but my access log is showing TCP_MISS for gif files. I believe the cause is SO_Fail but I don't know the fix for SO_Fail. My cache log looks clean.
