Package: linux-image-2.6.26-2-686
Version: 2.6.26-19lenny1
Severity: normal
Hi,
I have just had a hang on my machine, then running 2.6.26-19. The last
things I could see on the console was about 10 lines of these:
nf_conntrack: table full, dropping packet
The machine required a hard reset to come back to life. In my
/etc/sysctl.conf, I already have some adjustments:
net.core.rmem_max = 6777216
net.core.wmem_max = 6777216
net.ipv4.tcp_rmem = 4096 87380 6777216
net.ipv4.tcp_wmem = 4096 65536 6777216
net.ipv4.netfilter.ip_conntrack_max = 485760
vm.mmap_min_addr=4096
My logs looked benign to me.
I'd like Linux to handle the situation more gracefully, retaining at
least responsiveness to console operations.
Kind regards,
--Toni++
