[Dovecot] virtual folder - crash while searching

[André Rodier]

Hello everyone,

I had the same errors on my server, and I fixed it by increasing the
header size buffer of my server to 65535, for instance.

For jetty, the option is named headerBufferSize. See:

<Call name="addConnector">
  <Arg>
      <New class="org.mortbay.jetty.nio.SelectChannelConnector">
        <Set name="host"><SystemProperty name="jetty.host" /></Set>
        <Set name="port"><SystemProperty name="jetty.port"
default="8080"/></Set>
        <Set name="maxIdleTime">30000</Set>
        <Set name="Acceptors">2</Set>
        <Set name="statsOn">false</Set>
        <Set name="confidentialPort">8443</Set>
        <Set name="headerBufferSize">65536</Set>
    <Set name="lowResourcesConnections">5000</Set>
    <Set name="lowResourcesMaxIdleTime">5000</Set>
      </New>
  </Arg>
</Call>

No need to do this.
