We are running BSDI 2.0. Our kernel keeps reporting to the syslogger (hundreds of times a pop) "nfsd send error 55" Does anyone know what this means? I scanned through the RFC's on NFS, and was unable to find any leads. % grep 55 /usr/include/sys/errno.h #define ENOBUFS 55 /* No buffer space available */ I would appreciate some help! Has anyone else encountered this problem? What causes it? How do I fix it? Looks like your system is out of network buffers. This is Bad News. Either your system has a kernel bug which means that discarded buffers are not being freed properly or else it's handling more network activity than it can cope with. The former is possible - expecially if you've added or hacked a network device driver. The latter may be fixed by building a new kernel with a bigger buffer pool or else moving some of the network loads to another system. Consult your documentation and/or your OS support company.
