Hello Toby, Thanks for your reply. I looked at those number after a restart and they now look like: Total number of objects in the database: 10585 Total number of objects in all caches: 355 Target Size: 400 Target max time between accesses: 60 I didn't know that top two numbers were dynamic. Since the balance has changed, I'd like to leave them alone for now.

Now I am able to go to /control_Panel/Database. In fact, I am looking at info under Cache Parameters tab: Total number of objects in the database: 10561 Total number of objects in all caches: 2294 Target size: 400 Target max time between accesses: 60

Do they (bottom two, in particular) look reasonable? Please tell me what they mean or what they should be like. And what are the units on these? MB, KB?, seconds?, miliseconds?

400 is objects per thread. If you have the default 4 threads (and assuming you are not using versions) then it is interesting to note that 2294 is much bigger than 4*400 That indicates you have memory pressure. This might be the cause of your problem. If so, you could try: * doubling the target size, and perhaps halving the number of threads. * upgrading to 2.6. the cache manager was rewritten and is much better behaved. -- Toby Dickenson http://www.geminidataloggers.com/people/tdickenson
