    Memory leak in Asuswrt-Merlin

    A small memory leakage is still present... still coming from OpenVPN I think. But overall this is a trickle compared to the flood it used to be. My stats after almoust 28 days uptime: 148 MB free. So it lost almoust 50 MB from where it starts. I have continually been connected with an OpenVPN...

    Memory leak in Asuswrt-Merlin

    The leak is there in OpenVPN for sure. Still it may be connected to my exact OpenVPN settings. For example I use a TAP interface which I think is less common. As proof I have 4days 10h of uptime right now and 184 MB free. Right now on the old version I would be in at around 140 MB.

    Memory leak in Asuswrt-Merlin

    It is still too early to give any definite answers, but 380.58 seems to fix the issue (or at least improve it to the point where it is not so noticeable). After 10h uptime the free memory hovers around 200 MB. On prior versions it would already be at 190 MB. I will come back later, but for now I...

    Memory leak in Asuswrt-Merlin

    I think I have found the leak/cache that is using up the memory. After the discussion with highwire I thought about disabling the OpenVPN server since it was the only difference I had with his configuration and behold for 5h the memory usage has not increased at all. As soon as I disabled...

    Memory leak in Asuswrt-Merlin

    My traffic is more liniar in the tens of GB. The used RAM is over 29% right now of 250 RAM. One thing I will try it is disable the OpenVPN server. That seems to be the only special thing I have on my router.

    Memory leak in Asuswrt-Merlin

    How much traffic do you do daily? I only have OpenVPN server on it... nothing else extra.

    Memory leak in Asuswrt-Merlin

    You are right. I have created a spreadsheet with them, each information on a sheet. I will keep it updated. It can be viewed here https://docs.google.com/spreadsheets/d/1iJzWRuJCkbn8qqtEcYYALlw1KWVi8PqBY08isNi5pkY/edit?usp=sharing

    Memory leak in Asuswrt-Merlin

    Totally understand. I will update this thread on a daily basis with the latest stats. Hopefully I am mistaking and the increase will stop at some point.

    Here are this morning's results. The UI showed 187 MB free (20h uptime). 42@ASUS_RT-AC68U:/tmp/home/root# free -m total used free shared buffers Mem: 255720 64604 191116 0 2336 -/+ buffers: 62268 193452 Swap: 0 0 0 42@ASUS_RT-AC68U:/tmp/home/root# cat /proc/meminfo MemTotal...

    Memory leak in Asuswrt-Merlin

    I have tried it now, but it is not clear since the used memory hasn't climbed up sufficiently to notice the difference. Here is the output: ASUSWRT-Merlin RT-AC68U_3.0.0.4 Mon Nov 2 14:58:44 UTC 2015 42@ASUS_RT-AC68U:/tmp/home/root# free && sync && echo 3 > /proc/sys/vm/drop_cach es && free...

    Memory leak in Asuswrt-Merlin

    Yes that is exactly the same behavior. I had to do a restart some 6h ago and my current stats is 196 MB free. If I do df -h /tmp: 42@ASUS_RT-AC68U:/tmp# df -h /tmp Filesystem Size Used Available Use% Mounted on tmpfs 124.9M 412.0K 124.5M 0% /tmp 42@ASUS_RT-AC68U:/tmp# So the temp file...

    Memory leak in Asuswrt-Merlin

    Well a continuous decrease in memory might prove just that. Now it is at 178 free RAM, with some 2,5 MB for buffers. Nothing has changed in its functionality since I booted it or even from last night, so nothing extra was enabled, only network traffic. Either it is the logs, some form of caching...

    Memory leak in Asuswrt-Merlin

    I am a Windows user, but I am aware of how Linux works. I program in Java a lot and the way the garbage collector works generates the same behavior... freeing memory only when needed. This is what PuTTy gives me: 42@ASUS_RT-AC68U:/tmp/home/root# free -m total used free shared buffers Mem...

    Memory leak in Asuswrt-Merlin

    I have noticed the decrease about 10 days ago on 3.0.0.4.380.1842. I checked daily and after about almoust 5 days the free RAM was around 140 MB (down from around 190 MB). Last night I installed yours (btw the Stealth Mode is great... I cannot understand why Asus didn't implement that directly)...

    Memory leak in Asuswrt-Merlin

    Hello. First of all thanks for this wonderful firmware. I really appreciate the focus on stability. However I would like to report and issue. I have noticed on my RT-AC68U what I consider to be a terrible memory leak in both the official firmware and in Asuswrt-Merlin one. In fact I have...
