I have it set to 419430400 (400MB) on my 2 and 4G RAM servers. I have recently upgraded 5 NFS servers from 5.3-STABLE to 5.4-RELEASE- p2, and have had no ill effects so far. I had frequent crashes on 5.2.x before setting kmem_size_max (it was a compile time option back then), so I have kept it that way since.

NFS on 5.4
Hello ! Does anyone knows, what's going on with NFS on 5.4 ? I have same hardware as before, when 5.3 was installed, except the installation is new, 5.4. I have NFS mounted and some FTP app is using it extensively and server crashes once / day. I have noticed: After 8 hours of uptime... su-2.05b# netstat -m 739 mbufs in use 736/32768 mbuf clusters in use (current/max) 0/3/4464 sfbufs in use (current/peak/max) 1656 KBytes allocated to network 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile 749 calls to protocol drain routines suddenly after 5 minutes... 4294962365 mbufs in use 359/25600 mbuf clusters in use (current/max) 10/37/6656 sfbufs in use (current/peak/max) 4193789 KBytes allocated to network 0 requests for sfbufs denied 0 requests for sfbufs delayed 1453 requests for I/O initiated by sendfile 0 calls to protocol drain routines soon after that ... 4294961974 mbufs in use 358/25600 mbuf clusters in use (current/max) 10/37/6656 sfbufs in use (current/peak/max) 4193689 KBytes allocated to network 0 requests for sfbufs denied 0 requests for sfbufs delayed 1729 requests for I/O initiated by sendfile 4 calls to protocol drain routines Any clue ?

Re: NFS on 5.4
Aha, ok, thanks... (31 Oct 2004) The results of netstat -m can become incorrect on SMP systems when debug.mpsafenet is set to 1 (default). This is an error in the statistics gathering because of a race condition in the counters, not an actual memory leak. I'll put kernel into debug and see, as Max suggested.
