Do you still use Cubase 32bit?
Do you wonder why Cubase crashes after a while?

Consider the following test:

Start Cubase, 32bit version and do not open a project. Just double click the icon.
Open task manager and have a look at memory consumption.

My observations: Cubase 5.5.3 needs about 113 MB after starting, after 10 min 130MB and after 23 min 150MB and so on...

Without doing anything than checking for a valid license and waiting for action.
This gets worse while letting a big project play (up to adding 1MB every 4 sec with Superior Drummer and 4 instances of Melodyne).

If memory full = crash... (preferably blaming a plugin)

Cubase 5.5.3 64bit does not do that!
For testing I started without any plugins -> same result!

I run Win 7 64bit / RME Fireface and would be super curious whether someone could answer to this with the following details:

OS (32/64), ASIO card, memory delta after 10min, Cubase version

So in my case that would be Win7 64bit, RME Fireface, 17MB, Cubase 5.5.3 32bit

Support told me, that I'm the only one having this problem

I found evidence, that the problem might occur from 5.1 up to 6.0.5

Don't know anything about the memory leak but Cubase 32-bit is known to crash on Windows and Mac when around 1.5 GB of RAM is used for the process. Logic does the same in 32-bit mode.

This is one of the reasons why it's good to go 64-bit ASAP ... if your plugins support it.

Peace,
Andy.

Did the test. Win 7 64 bit Home, M-Audio 2496, 4 GB RAM, Cubase 5.5.2, 32-bit. Memory after 5 minutes is the same as at 1 minute: 125 MB. No project loaded ...

Peace,
Andy.

My installation crashes at about 3 Gig...
The theoretical values should be 2 Gig or 4 Gig according to Microsoft:

Jep, the last point is my problem.

I have no problem with buying new plugins, but not for the sole reason that Cubase has a memory leak. This is what I want to find out...

Thank you!!!
So that leaves only the RME drivers or some 32/64 bit bull**** accessing them.

I'm puzzled...

Doesn't crash here on Win7(64bit) Cubase 6.0.5(32bit) 6gb ram.
It can load atleast 3+ gigs of ram on its own without problems..
Haven't had bigger projects so far.. and when i do i can always bridge stuff.

I'm testing that memory leakage thing right now

Interesting to see what happens.

edit: five minutes to the test i'm down 0.5mb.. so it's using less memory.

OK, that's good to know. I've seen other people post about the 1.5 GB problem, so maybe it's related to system spec, drivers or plugins ...

Peace,

Thank you for having a look at it.

I'm a bit speechless. I have a very clean installation and the first thing
after seeing this was to update everything. I do IT for a living and worked
on big software. But this behavior is really strange...

I did some further testing:

- ejected CodeMeter dongle -> No change
- started with no audio driver -> 115'352 no leak... going down a bit

So I will have to investigate the RME side of things a bit more.

Thanks for looking into this, helped a lot.

I've had Cubase running in the background(8 audio channels open) for an hour with no change to the memory usage. I guess you can blame the RME driver based on your tests..

I have not noticed anything similar on Cubase 5.5.3. 32-bit, but will have a look later today. Only reason for crashing for me have been plugins.

Well I tested further:

No Driver = No memory leak
Asio DirectX Full Duplex Driver = Leak after restart
Generic Low Latency ASIO Driver = Leak after restart

So I guess there is something wrong with ASIO.

I reenabled my internal soundcard and deinstalled the RME stuff.

After a reboot memory still goes up, as quick as before.

So it's not in the RME stuff either.

I also tried the MultiProcessing flag -> no change

What graphics?
I'm on Nvidia Geforce 9800GTX+ driver 285.62

That was my first guess too, since the plugin that pushes you over the memory boundary will be reported as the offender.

Melodynes exceptional quick and knowledgeable support team pointed me to memory.
Then I came up with that little insane test

When I start working on a big song that starts with 1Gig, after working for a while (without adding more stuff) that takes 2Gig. And around 3Gig I can crash
Cubase reproducable.

I will have a look if I can write a small program that monitors the memory consumption and give a warning when a threshold is reached

Good point! Nvidia 9600 GT with a driver from 2010 (8.17.12.5896) :-/
Just updated to 285.62, unfortunately same problem...

Does Cubase 5/6 32bit has a memory problem??? Simple test to find out...
