I noticed my computer running low on memory, and found that exiting BOINC freed me 3 gigs or so. I opened task manager and found that boincmgr.exe (which had been running about 18 hours) was taking over 2GB of memory before I shut it down--but when I restart BOINC, it only takes about 23MB.

Repeat: it's not the apps nor the boinc client, but boinc manager (boincmgr.exe) taking up all the memory.

Here's the config I've been using:

Try 7.0.44 ... there was mention of at least 2 memory leak fixings. Personally not seen it and been running 7.0.42 and .44 for as long as they've been available on multiple hosts, used or crunch only, noting that most of the time I don't leave the BM loaded. I use BT mostly.

When you aren't using some of the debug-logging flags, disable them. You don't need cpu_sched_debug, rr_simulation or work_fetch_debug for finding out what causes your 'exit but no finished file' problem.

There's been a long standing bug in BOINC Manager (the GUI) that causes old log entries not to be deleted from the memory that BM uses. Adding too many flags can cause this bug to pop up.
