Summary 0001190: random 503 error codes
Description Have the following configuration: 4 RedHat AS 2.1 servers running apache 2.0.48 on the front-end (mod_caucho) and 2 RedHat AS 4.0 servers running resin 3.0.18 on the backend.

We recently upgraded from resin 2.1.5 to 3.0.18 and started seing random 503 errors in apache logs. The errors do not seem to be correlated to load on the servers or any specific activity.

Any help would be appreciated.
Additional Information from resin.conf on the backend:

  <thread-pool>
    <!-- Maximum number of threads. -->
    <thread-max>400</thread-max>

    <!-- Minimum number of spare connection threads. -->
    <spare-thread-min>25</spare-thread-min>
  </thread-pool>


    <keepalive-max>350</keepalive-max>
    <keepalive-timeout>120s</keepalive-timeout>

    <cluster>
        <client-live-time>110s</client-live-time>
        <client-read-timeout>120s</client-read-timeout>
        <client-dead-time>10s</client-dead-time>

        <srun id="a" host="10.24.217.1" port="6802" index="1" tcp-no-delay="true" read-timeout="120s"/>
        <srun id="b" host="10.24.217.2" port="6802" index="2" tcp-no-delay="true" read-timeout="120s"/>

 We are seeing similar random 503 errors in the log with resin 3.0.18 and apache 2.0.55 (mod_caucho-3.0.18). If we hit resin directly the errors to not occur, but via apache, small things like style sheets, links stop working...

 We are seeing this behavior with resin 3.0.19 and apache 2.0.55 as well.
