[Dovecot] kernel problem in RedHat? -- RH specific, or what linux kernels does this affect?

[Linda Walsh]

Is this redhat's version of the kernel only?  Or does it apply to other 
linux kernels and other distros?

Any idea what linux kernel versions might cause this?

Red Hat/CentOS users: A recent kernel update 
<https://bugzilla.redhat.com/show_bug.cgi?id=681578> causes Dovecot to 
start failing after it has reached 1000 child processes. To fix this, 
downgrade your kernel until Red Hat releases a fixed kernel.
