src/lib/libc/gen/syslog_r.c, 188: * If the sendsyslog() fails, it means that syslogd * is not running or the kernel ran out of buffers. sendsyslog(2) RETURN VALUES Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error. errno(2) 55 ENOBUFS No buffer space available. An operation on a socket or pipe was not performed because the system lacked sufficient buffer space or because a queue was full. But I can't tell you why your kernel is running out of buffers. You did not give much information... Marcus > !DSPAM:588f7557249121949212877!
