Suricata memory leak on OPNsense 19.1.10-amd64?

« on: July 14, 2019, 09:59:37 pm »

Hello,

I have noticed during a huge file transfer over SMB that suricata started to use up to all memory (16 GB RAM) on my 19.1.10-amd64 machine. That can't be normal.

Suricata is on version 4.1.4_2.

I would recommend reporting this upstream because we can only speculate from here.

OK, thanks.

I'll report it upstream. Was just curious if others experienced a similar behavior. I have suricata running for several years now and never observed something like this.

SMB received a couple of updates in 4.1 so maybe that's that. Newer decoders are written in Rust which are supposed to be leak-proof so I guess this thing is not because it's not written in Rust.
