Subject: i686 SMP systems with more then 12 GB ram with 2.4.x kernel ?
Date: 29 Dec 2001 19:18:17 +0100 [thread overview]
Message-ID: <1009649897.12942.2.camel@hh2.hhhome.at> (raw)
Are there some i686 SMP systems with more then 12 GB ram out there ?
Is there a known problem with 2.4.x kernel and such systems ?
I have the following problem:
A Intel SRPM8 Server with 32 GB ram and RH 7.2 and kernel 2.4.17 on it.
After doing a lot of disc access the system slows down and the oom
killer begins his work. (only after running some cp processes.)
Because the system is running out of low memory.
Disable the oom killer has no affect, the low memory is going to 0
and the system dies.
It looks like as the buffer_heads would fill the low memory up,
whether there is sufficient memory available or not, as long as
there is sufficient high memory for caching.
Any ideas ?
Here some information from /proc/meminfo and /proc/slabinfo some
seconds before dying:
