On one of my internal nfs test boxes, I have noticed that kernels from March 28th and April 6th r332100 ended up with devd running out of swap space and being killed at some point. First time I thought perhaps a fluke due to some stress testing I was doing. But I left the box running over the weekend and Sat AM it died at 3:51am (perhaps when periodic runs?) I have lots of free memory, however, ARC is chewing up 27G of the 32G. CPU: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 800K Active, 15M Inact, 9964K Laundry, 30G Wired, 516M Free ARC: 28G Total, 4996M MFU, 23G MRU, 5440K Anon, 78M Header, 593M Other 27G Compressed, 28G Uncompressed, 1.04:1 Ratio Swap: 20G Total, 21M Used, 20G Free Anyone else seen anything like this on a recent RELENG11 STABLE ? ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 x203 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada
