FreeNAS crashing constanly

[SoftDux-Rudi]

Hi,

I have a FreeNAS server which constantly crashes, for the past week or so. The server is in a remote location and I asked a tech to connect a screen to the server, and this is what he got:

Code:

panic: kmem_malloc(36864): kmem_map too small: 332560 total allocated
cpuid = 0
Uptime: 9h50m57s
Cannot dump.  Device not defined or unavailable.
Automatic reboot in 15 seconds - press a key on the console to abort

I don't have the server specs with me right now, but will update this post once I do.

Does anyone know what could cause this?

It means you don't have enough RAM allocated in kernel space.

How much RAM have you got? x86 or x64? Do you have any tunables in System -> Tunables?

The server has 4GB RAM, and can't take any more but it looks like FreeNAS only sees 3.3GB:

Code:

FreeNAS-8.0.4-RELEASE-p2-x86 (11367)
Platform
Intel(R) Pentium(R) 4 CPU 3.00GHz
Memory
3305MB
System Time
Thu Oct 11 19:06:38 2012
Uptime
7:06PM up 2:24, 0 users
Load Average
0.27, 0.07, 0.02
OS Version
FreeBSD 8.2-RELEASE-p7

There are no settings in Settings > Tunables, what do you suggest I add ?

FreeNAS on x86 and that amount of ram usually dont go well...

You can try upgrade to 8.2.0 and enable autotune, that _might_ help.

Ok, will do.

Sorry, I forgot to say. There's 4 drives in the server with ZFS:

Name	Status

​ Tank	ONLINE
​ mirror	ONLINE
​ ada0p2	ONLINE
​ ada1p2	ONLINE

I had the same error message. For me it wasn't a ram issue but maybe yours is. They only way I could get to my files was through ztp. I use filezilla to ztp into my freenas box and managed to transfer all of my files over to another computer.

If you can't fix it try the ztp.

That's normal for a 32-bit operating system. If you want to see the full 4GB, you need to use the 64-bit version of FreeNAS.
