A number of fixes related to this went into the RHEL3 U4 kernel, which was released yesterday. Could you please confirm whether or not this problem is still present in kernel-2.4.21-27EL ? I believe that the latest kernel should fix your problem. The RHEL3 U4 kernel advisory is RHBA-2004:550. Joe, we are still waiting for confirmation that this problem has been fixed in then latest RHEL3 kernel. Can you verify this so we can close this bug? Thaank You, Larry Woodman
Joe, we are still waiting for your verification that the RHEL3-U4 update fixed
this problem. Your system exhausted lowmem in the slabcache:
>>>197896 pages of slabcache
The previous version had a problem reclaiming inodes from the inode cache which
are allocated form the slabcache. I fixed that problem in U4, can you verify
this so I can close this bug?
Thanks for your help on this Joe, Larry Woodman
I have a server with 16gig of memeory running Oracle and Informatica. The kernel is 2.4.21-27smp and I am experiencing the same memory issues. The applications appear to be exhausting the lowmem. I have over 10 gig of highmem available. Michael, please attach the show_mem() output that is written to /var/log/messages when the OOM kill occurs so I can see where the lowmem on your system is going. While you are at it please get a "/proc/slabinfo" output just incase your slabcache is consuming all of lowmem as well. Thanks, Larry Woodman Created attachment 114775 [details]
Out of memory error
The attched showmem is from 16GB system running the SMP kernel. Lowmem is totally exhausted with the mem_map and slabcache!!! Please use the Hugemem kernel and this problem will go away. Larry Woodman Closing due to lack of reporter's response to comment #1. |
