I have seen this problem on i386 only so far. Version-Release number of selected component (if applicable): Both client and server were RHEL4-U6 GA distros. httpd-2.0.52-38.ent httpd-suexec-2.0.52-38.ent kernel-2.6.9-67.EL How reproducible: Always
Were you using the default httpd.conf? That has: MaxClients 256 so it is unsurprising that you see ab errors for concurrency of 500.
Yes, I was using that default setting.
This is not entirely surprising behaviour then. Use a smaller concurrency setting or increase MaxClients and ServerLimit.
