Hi,
I am getting following messages in my /var/log/messages. Not continuous
but often.
kernel: NET: 555 messages suppressed.
kernel: NET: 556 messages suppressed.
kernel: NET: 546 messages suppressed.
kernel: NET: 557 messages suppressed.
I have RedHat 7.3 with Kernel 2.4.18 and running squid 2.5 (Transparent).
I have Traced back to its source in /usr/src/linux-2.4/net/core/utils.c
and found
* This enforces a rate limit: not more than one kernel message
* every 5secs to make a denial-of-service attack impossible.
....
if (lost)
printk(KERN_WARNING "NET: %d messages
suppressed.\n", lost);
return 1;
...
Is the kernel taking many concurrent requests as DOS attack and
suppressing the requests. Can any one help how this can be resolved?
Thanks in advance.
