I have recently had my system crashing under high NFS load. I could reproduce it with no problem, and it seams to happen with 1 NFSv3 linux client, uploading big files (the crash happens after 300-400 Mbytes). Note that i've had the same "success" with -STABLE and 4.4-RELEASE. Just before crashing, syslog says "m_clalloc failed, consider increase NMBCLUSTERS value", and the system crashs a couple of seconds later. I did change the value of NMBCLUSTERS to 8192 (default is something around 1024), and it really fixed that problem. Is this usual to see systems crashing after unsuccessful m_clalloc() calls ? -- Regards Julien B To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
