I have been getting some unusual errors in my syslog output. Apr 5 14:11:40 hindmost unix: tcpcmds: non-fatal error in unknown event: 0000000B Apr 5 14:11:41 hindmost unix: NOTICE: growreg - Insufficient memory to allocate 52652 pages - system call failed Apr 6 07:17:35 hindmost unix: NOTICE: getcpages - waiting for 1 contiguous pages The growreg and getcpages errors ocasionally show up with a non-fatal error from tcpcmds as in the above case. They are always related to receiving an incoming ftpd/telnetd/rlogind connection. Ocassionaly the messages are repeated several times. However, the incoming connection always seems to work. Here is the output from netstat -m. Occasionally there will be something in the 'fail' column, but the Max is usually well below the allocated, so I suspect it is trying to allocate a large number of blocks at once and failing, rather than trying to allocate them on the way up. alloc inuse total max fail streams: 160 63 46039 87 0 queues: 640 352 272872 492 0 mblocks: 2327 435 9915274 746 0 dblocks: 1862 417 8609838 743 0 dblock class: 0 ( 4) 256 8 151170 205 0 1 ( 16) 256 36 829327 207 0 2 ( 64) 384 155 5944361 170 0 3 ( 128) 600 194 562355 271 0 4 ( 256) 128 3 215176 78 0 5 ( 512) 128 10 227163 20 0 6 (1024) 50 11 407849 38 0 7 (2048) 30 0 270303 27 0 8 (4096) 30 0 2134 11 0 This system does have NFS installed, and several remote mounts to it. It also only has 8 Mb of memory, and frequently gets 10 or more users logged in at the same time. Any suggestions on how to fix this problem, would be appreciated. -- Stu --
