No I guess the maximum value is 64K. Yes. It did crash my machine. Just FYI, I tried this before on my 64M RAM linux box. The default is 4K connection max. But I tried to increase it to 64K. End up when the number of connections grow to 13K (based on /proc/net/ip_conntrack), it first starts killing my other processes including klogd, syslog-ng, snort. At this time, you can see the kernel start killing the process from your syslog (before syslog died) After a while my linux box hang. And wait for reboot I guess this is related to OOM (out-of-memory) bug in the kernel (I'm using 2.4.18-xfs). .//Jet > > If I increase the value what negative effect does it have???
