[Duplicate] Multiple sldb process full the CPU load…

SurfceS

My boxes are really slow after 1 day running, and are completelly unbrowsable after few days.
Load CPU is 100 % after only 20 minutes.

Hardware config :

DELL PowerEdge 860

Intel(R) Xeon(R) CPU 3040 @ 1.86GHz (Dual Core)
1GB 667Mhz DDR2 SDRAM

ad10: Seagate ST3750640NS 3.BKE (Capacity: 732.87 GB)

bge1: Broadcom BCM5750 B1, ASIC rev. 0x4101

Here is a time to startup process load (all in normal usage with clients on it):

After about 20 minutes :

And few days after, I need to restart the box if I want it to be in consistent state.

Any others have the same problem, or I'm really not lucky, and both servers are misconfigured/buggy ?

Best regards,

I've attached the http://pfSenseBox/phpSysInfo/ result.
The other strange thing, is the buffer line, on the memory usage tab… It full up the memory.

FYI, the internet line is not really used the WE (as you can see on the page).

After connecting to the box thru ssh, and run :

/usr/bin/killall -9 slbd
/usr/local/sbin/slbd -c/var/etc/slbd.conf -r5000

After that, everything become fine as if I've restart the box.

But it still overload my box few by few, fulling it with slbd process.

Strange case I have…
