-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In my case, I can almost set my watch to it (if I had a watch) ... every 3 days, 2 hours, it seems that I have to reboot this machine, as that is when the 'No Buffer Space Available' r starts to be generated ... There are two others (CC'd in this) that have experienced the same ... Chris / Thiago ... in your cases, are you finding that it happens as regularly with your servers? Thiago, I believe you ended up reverting to an older kernel to clear up the situation? I've included my 'netstat -m' report ... from it, it doesn't look to me like its an mbuf issue, or am I missing something? Is there something else that, in 74 hours, I can provide before I do the reboot? Chris, you mentioned reducing recvspace/sendspace to correct the issue? Has that fixed it for you, or just prolonged until it happens again? How did you set this? I've checked both the man pages for ifconfig and fxp, and don't see anything ... ah, just found it doing a 'sysctl -a' ... can you post your settings from /etc/sysctl.conf? or did you set it somewhere else? I'd like to try that and see if maybe that changes my '74 hours uptime', either good or bad ... # netstat -m 161/949/1110 mbufs in use (current/cache/total) 133/639/772/25600 mbuf clusters in use (current/cache/total/max) 133/396 mbuf+clusters out of packet secondary zone in use (current/cache) 0/0/0/0 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/0 9k jumbo clusters in use (current/cache/total/max) 0/0/0/0 16k jumbo clusters in use (current/cache/total/max) 306K/1515K/1821K bytes allocated to network (current/cache/total) 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0/45/6656 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 325 requests for I/O initiated by sendfile 731 calls to protocol drain routines - ---- Marc G.
