grsecurity forums

Hi
I had installed grsecurity for kernel 2.4.24.
Most things work fine, but i have a problem: sometimes when i give instruction from
root level
netstat -ta
i got correct table of connections as an output, and sometimes i
got:
netstat -ta
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign
Address State
/proc/net/tcp: Permission denied

The same problem occurs for "route":
route
/proc/net/route: Permission denied
INET (IPv4) not configured in this system.

there is no rule, sometimes o got right answer, and sometimes i
got error.
It gets a little iritating. The same thing have place with
netstat -ta from user level.
With option can cause this??
In Network Protection I have only "large entropy pools" marked.
linux slackware 9.1
