[LON-CAPA-admin] caching of id -> failed

[H. K. Ng]

Hi Guy,

The lonnet.log file seems to be filled with the caching of id failed 
message - it is about 300 MB in size. There are also a lot of

Userfile repcopy failed for 
uploaded/fsu/54412611fd3c9469bfsul1/default_1155048274.sequence.meta
messages. (As you mentioned before, this is not a real error message.)

Is all this writing to disk affecting the server performance. If so, 
is there some way to turn them off?

Thanks,
-hk

Checking the entries on lonnet, it should be mdr04c. He was accessing
However, the last time this person logged in was in December.

It looks like he is accessing

in./fsu/414744126dac946cdfsul1

It is a chemistry lab course for this coming fall. The time stamps on
the id -> failed starts a second later.
