Subject Lateral TCP consuming memory
Date Thu, 15 Oct 2009 07:03:46 GMT
Hi,

I configured Lateral TCP, so as to make caches on 2 servers to be
consistent. All i require is GET from other server to be false.
When i check the the cache just after the server starts, it shows me > 30MB
of space taken up by mitCache with 0 objects in it. Please suggest where the
memory leak.

Note: without LTCP, memory size is around  300KB


Here is the following snippet of configuration (cache.ccf),

#For LTCP Cache
jcs.default=LTCP
