I frequently see this in my httpd error_log. I don't know what it means, any help would be appreciated.
Thanks

[date time] [level] "message"
In general the second field denotes the severity level of the logged message, info and notice could both be regarded as "informational", anything higher is a warning or error you should respond to.

The "Cannot remove module" means you should reconfigure your httpd.conf's ClearModuleList and include those modules source that a warning is issued for.

The mod_mime_magic I'm not sure about, I think you need to check your "magic" files against corruption.

I agree with unSpawn, it looks like your magic file is messed up!
