net-tools-1.41-3 netstat 1.37 (1999-01-31) RH6.0
When running netstat in continuous mode like in
netstat -c -i
tho process will open a new file descriptor on every
cycle until eventually the process rouns out of available
Running with strace confirms that on every cycle an
open of the file "/proc/net/dev" id done, but that file
is never closed.
Fixed in net-tools-1.52-3. Thanks for the report.
