kmem_map too small: 260046848 total allocated
...... First scan through Google, I came across some posts talking about NMBCLUSTERS ... since its at the same settings as my other server (the default) and it hasn't experienced similar problems, I'm guessing that that isn't the cause ... Now, on neptune (the one with issues), I have KVA_PAGES set to 292, which, when it crashed, had vm.kvm_free: 104857600 available (I had it at the default 256, and kvm_free drop'd to 0 within 24hrs, so I raised it a little bit to give it some buffer space) ... but never raised the VM_KMEM_SIZE values above their defaults ... Is there some tunable...

6.3-RELEASE-p3 recurring panics on multiple SM PDSMi+
We have 10 SuperMicro PDSMi+ 5015M-MTs that are panic'ing every few days. This started shortly after upgrade from 6.2-RELEASE to 6.3-RELEASE with freebsd-update. Other than switching to a debugging kernel, a little sysctl tuning, and patching with freebsd-update, they are stock. The debugging kernel was built from source that is also being patched with freebsd-update. These systems are

[SO]HO Software RAID5 server: which implementation should I choice?
Hello, freebsd-stable. Does somebody use some software RAID5 on FreeBSD in real production system? I want to build storage server for my home: RAW photos, multi-layer PhotoShop files and FLAC-encoded music consume a lot of space, and they should be availible both from desktop & notebook. Also, all photo-content is unique, so I need some insuranse from single HDD crash. I understand,
