So this has happened to me 3 times now: I have left my computer on over night and when I come back in the morning all of my ram is being used and about a third to a half of my swap space is full. Here's some information that may or may not be pertinent:I have 7.8GiB ram and 8GiB swap.I am running Linux Mint Petra with cinnamon 2.When I look at system monitor while this is happening no process isusing an inordinate of memory and all 8 cores of my CPU are running sub 10%Aside from my start-up applications, the only thing I have runningovernight is firefox idling on my open tabs. I have only added Guakeand Cairo Dock to my start-up apps in addition to the default Mintstart-up applications.I have installed jack and therefore some of my memory limits mayhave been changed. This is the output from ulimit -a:core file size          (blocks, -c) 0 data seg size           (kbytes, -d) unlimitedscheduling priority             (-e) 0file size               (blocks, -f) unlimitedpending signals                 (-i) 61806max locked memory       (kbytes, -l) 64max memory size         (kbytes, -m) unlimitedopen files                      (-n) 1024pipe size            (512 bytes, -p) 8POSIX message queues     (bytes, -q) 819200real-time priority              (-r) 0stack size              (kbytes, -s) 8192cpu time               (seconds, -t) unlimitedmax user processes              (-u) 61806virtual memory          (kbytes, -v) unlimitedfile locks                      (-x) unlimited(I think that I had not installed jack the first time this happened, though I am not positive)I have done some anti-virus things including, but not limited to, completely reinstalling my system between incident 2 and 3. Also incident 3 came on night 2 after reinstall. All anti-virus things seem to indicate that my computer is clean.I had to leave in the middle of writing this question. I was gone for 12 hours. Aside from my start-up apps, firefox, system monitor, and my Downloads folder were still open: my memory usage has gone from about 1.1-1.2 Gib when I left to 1.6 GiB now. So my questions are: (a) Is this indicative of a memory leak? I don't quite know what a memory leak looks like. (b) If yes, how do I ferret out the culprit? (c) If no, is there anything else I could start looking at?
Is there some memory leak in Mint 16? Or else what is this?
