[Bug 1131019] Re: ip range scan with fping lasts six times
Hi Christopher,
your link about EOL of Lucid tells (as i could remember) that Lucid Server's EOL will be in April 2015.
I'm sorry, but i can't burn the iso and test new release as it's too much effort for me at the moment.
The bug may be easily reproduced with Lucid running fping on a Pentium I/AMD-K6-machine using Kernel 2.6.32-44-generic (no bug) and Kernel 2.6.32-45-generic (fping 6 times slower), as same bug occurs on two different machines (PI/AMD-K6-Processor) working as network routers. There seems something related to the bug changed between those kernel versions.
