Memory leak and RAM usage

[kroeckx]

Hi,

The electron version uses 12 GB of RAM just after starting. This will grow over time, and I've seen it use 60 GB of RAM.

I'm using the .deb package from riot.im. currently using version 1.2.2, but it's not a new problem.

That’s crazy - for typical use it should use about 300MB resident (rsz); up to 1GB for worst case massive account. What RSZ are you seeing? And how big is the javascript heap? (ctrl-shift-I to open the inspector; go to performance tab; hit heap snapshot to see where the RAM is going).

A few minutes after I started it, I get: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND kurt 8021 4.7 3.5 1242136 284376 pts/5 Sl+ 17:05 0:16 | \_ /opt/Riot/riot-web kurt 8023 0.0 0.4 210664 40136 pts/5 S+ 17:05 0:00 | \_ /opt/Riot/riot-web --type=zygote --no-sandbox kurt 8051 28.5 7.9 12987672 638572 pts/5 Sl+ 17:05 1:41 | | \_ /opt/Riot/riot-web --type=renderer kurt 8087 13.6 10.2 1638764 828360 pts/5 Sl+ 17:05 0:45 | | \_ /opt/Riot/riot-web --type=renderer kurt 8046 2.1 1.4 361956 117748 pts/5 Sl+ 17:05 0:07 | \_ /opt/Riot/riot-web --type=gpu-process

And how big is the javascript heap?

It reports things around 300 MB.

[ara4n]

right, so that’s 284MB + 40MB + 640MB + 828MB + 118MB of resident RAM. however, some of that might be shared libraries shared between the processes?

Will compare with other electron deployments.

300MB js heap is about right.

So looking at the smaps file, I see things like: 32089a940000-320a9a900000 ---p 00000000 00:00 0 Size: 8388352 kB KernelPageSize: 4 kB MMUPageSize: 4 kB Rss: 0 kB Pss: 0 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 0 kB Referenced: 0 kB Anonymous: 0 kB LazyFree: 0 kB AnonHugePages: 0 kB ShmemPmdMapped: 0 kB Shared_Hugetlb: 0 kB Private_Hugetlb: 0 kB Swap: 0 kB SwapPss: 0 kB Locked: 0 kB VmFlags: mr mw me sd 32081a900000-32089a900000 ---p 00000000 00:00 0 Size: 2097152 kB KernelPageSize: 4 kB MMUPageSize: 4 kB Rss: 0 kB Pss: 0 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 0 kB Referenced: 0 kB Anonymous: 0 kB LazyFree: 0 kB AnonHugePages: 0 kB ShmemPmdMapped: 0 kB Shared_Hugetlb: 0 kB Private_Hugetlb: 0 kB Swap: 0 kB SwapPss: 0 kB Locked: 0 kB VmFlags: mr mw me sd 149b8d9b1000-149bcd942000 ---p 00000000 00:00 0 Size: 1048132 kB KernelPageSize: 4 kB MMUPageSize: 4 kB Rss: 0 kB Pss: 0 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 0 kB Referenced: 0 kB Anonymous: 0 kB LazyFree: 0 kB AnonHugePages: 0 kB ShmemPmdMapped: 0 kB Shared_Hugetlb: 0 kB Private_Hugetlb: 0 kB Swap: 0 kB SwapPss: 0 kB Locked: 0 kB VmFlags: mr mw me sd So that's 8 GB - 256 kB, 2 GB, and 1 GB - 444 kB that's allocated but unused.

So I got his now:
[4:0812/224748.911437:FATAL:memory_linux.cc(42)] Out of memory.

I have to restart riot on daily basis because it just stops working.

[xsellier]

Riot is just using 11G or ram....

[t3chguy]

riot.im/develop (and next point release) fixes a lot of leaks.

@kroeckx, @xsellier, can you still reproduce this issue?
