logfile extract, processor, and memory information
This may be an NFS problem. I'll post more as I find it. Switching NFS mounts from UDP to TCP seem to have cured it. Stephen, can you also try increasing /proc/sys/vm/min_free_kbytes by 4 times its default and see if that fixes the problem when NFS is using UDP ? Thanks, Larry Woodman Doned (2003 -> 8012) but I cannot test until this weekend. I'll let you know what happens Stephen, did you get a chance to test that tuning suggestion in comment #4 yet? Larry Woodman Sorry to have taken so long. I made the suggested change and got the out of memory errors during that evening's backup which was still using TCP. I didn't try it with UDP then but rather just set the free_kbytes back to 2003. In the next week or so I shuold be able to bukd a replacetn Oracle server I'll have mor opportunit to experiment with.
