Hi, Story continues...
We have found out that during night/batch processing memory utilisation grows significantly after SSELECT is performed by the session. Moreover these memory blocks seem not to be reclaimed until process dies. We did a simple test after my colleague suggestion. Here are details: a) session A: login to jshell, check your port via WHO command b) session B: run SSELECT on large table with many IDs, preferably right justified or with some non-standard characters like asterrisk, comma, dot, question mark, etc. c) session A: quickly, meanwhile, run MW42 -p<port_number_from_session_A_WHO> and observe memory allocation Process will hit some number and stay at this level, say 200 MB which is still quite too much for me. Run a SSELECT on smaller table with lower number of IDs and observe memory allocation. Memory usage will stay at the same level, say 200 MB. Run a SSELECT on largest table you have with many IDs. You will see that additional memory is allocated at some point - say you will finally reach 400 MB. This sorting buffer seems never to shrink. I know that previously I suggested that perhaps "transaction buffer" is not downsized, but we can easily tell that session that runs SSELECTs can allocate more and more memory. I am confused and still does not know wheter memory leaks or not. We have also quickly changed to "MALLOCTYPE=watson" on test area and here is interesting output: jsh techuser ~ -->SSELECT <largetable> jBASE: Attempting to free NULL pointer at
