Squid fails to start

[asterix]

Just did a clean reinstall and now Squid fails to start. Exact same configuration as before. Even executed squid -z but has no effect.

Here is the log..

If I keep the "Level 1 subdirectories" to 16 it starts, but if I select 32/65/128 it dies with the same errors.

And the log shows below errors while the Squid service is up.

chown -R proxy:proxy /var/squid/cache

Not sure how what might have stomped on that.

I have tried that command already. That didn't work.

I figured out the issue. Not sure if it's something to do with the latest snapshots or Squid itself. Pretty sure its not Squid as this issue never came up in builds before April 10th.
When you install Squid the directory /var/squid/cache is deprived of system rights on "write" to a degree that Squid cannot crate the sub directories and fails to start.

What I did was.. installed Squid, configured it, rebooted. Squid fails to start on first reboot. Deleted /var/squid/cache directory through File Manager and then went into packages and did a Squid "reinstall" package. This time the reinstall creates the cache directory with the correct access permissions. Reboot again to ensure everything is in order.

I had one question on the level of Squid configuration. Please shed some light on this.

I have 4GB RAM and 120GB hdd.

What would be the best performance settings in Squid Cache Mgmt for..

1. Hard disk cache size = ? (I have it at 3000MB)
2. HArd Disk cache system = ? ( I have aufs)
3. Memory cache size = ? (I have 1000MB)
4. Minimum object size = ? (default 0 is fine??)
5. Maximum object size = ? (I have 256KB)
6. Level 1 subdirectories = ? (I have it at 16, should I go for more? If so how much?)
7. Memory replacement policy = ? (I have Heap LFUDA)
   8 ) Cache replacement policy = ? (I have Heap LFUDA)
