Hi,

I also don't think that cacheClientHttpRequests and
cacheCurrentLRUExpiration will work with MRTG. I am not using these 2
entries for my MRTG graphs because they were causing problems.

I think that your MRTG graphs for other values will work fine if you
remove or hash out these 2 entries from your cfg file.

Thanking you...
