I'm trying to understand if there is anything that I should do regarding the FAILs froma vmstat -z result ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP UMA Hash: 256, 0 , 5, 10, 13, 0, 0 4 Bucket: 32, 0, 113, 13637,56567851,1016721, 0 6 Bucket: 48, 0, 38, 10420, 5813437,1644722, 0 8 Bucket: 64, 0, 588, 10076,15183107,48522, 0 12 Bucket: 96, 0, 110, 1858, 4103705,87972, 0 16 Bucket: 128, 0, 835, 1583, 6158208, 1, 0 32 Bucket: 256, 0, 574, 2051,12819286, 10, 0 64 Bucket: 512, 0, 14016, 6008,13042857,4594231, 0 128 Bucket: 1024, 0, 1081, 7455,10754938,512246, 0 256 Bucket: 2048, 0, 1669, 2749, 2393011,1381094, 0 vmem btag: 56, 0, 65907, 49752, 5035839, 872, 0 I noticed the FreeBSD12 GENERIC kernel has an option regarding NUMA and thought I should understand the impact to my systems and how I can monitor the system for deviation (good or bad). (Its been a very long time since I've asked for help, but this isn't covered in my FreeBSD Design book - yes, paper! ;)
