[-- Attachment #1 --] Hi there, according to FAQ (http://www.freebsd.org/FAQ/troubleshoot.html#AEN1135) you can set the NMBCLUSTERS option in the KERNEL configuration to options "NMBCLUSTERS=<n>" where <n> is in the range 512-4096, my two questions are: 1. We have servers that this value is set as options NMBCLUSTERS=8192 is this normal to be that high even in FAQ the MAX is 4096. 2. The entry does not have a quotation mark around it as the FAQ does is it mandatory to have those quotation marks? when I issue netstat -m the settings are realized sine it reports 3187/3616 mbufs in use: 2890 mbufs allocated to data 297 mbufs allocated to packet headers 2546/2930/8192 mbuf clusters in use (current/peak/max) 6312 Kbytes allocated to network (86% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines The reason I'm investigating this is because I get a KERNEL panic and the server reboots. The message in the /var/log/messages states: /kernel: Out of mbuf clusters - adjust NMBCLUSTERS or increase maxusers! Any suggestions and ideas are appreciated,thanx. -- Majid Almassari, MSEE, MCP.
