Description of problem: After a while network crashes with error messages in /var/log/messages: kernel: dst cache overflow Version-Release number of selected component (if applicable): kernel-smp-2.6.5-1.358 How reproducible: Happens sometimes (once in three or four days). But when increasing the value of /proc/sys/net/ipv4/route/max_size to a high value and decreasing it later to a value lower then the value in grep ip_dst_cache /proc/slabinfo will chrash the network right away with the same errors in /var/log/messages. Additional info: I have already increased the value of /proc/sys/net/ipv4/route/max_size but this is slowing the server down and only delays the eventualy crash.
firstly, update your kernel. 2.6.5 is ancient, and a hurrendous number of bugs have been fixed since then.
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
