    Default Proble accessing zcs upstream server - Exceeded the max requests limit.

    Hi guys .

    On my environment I have a multi server installation, using zimbra 8.0.4 64bit open source edition and I have a very strange situation.
    Some users complained that while they was trying to log in, they saw the "Problem accessing ZCS upstream server. Cannot connect to the ZCS
    upstream server. Connection is refused." message.

    The same time on the /opt/zimbra/log/mailbox.log file of my back end mailstore server there are messages like the following:

    https://19.29.39.134:443/service/soa...iniCalRequest] [ip=19.29.39.112;ua=Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.57 Safari/537.36;] misc - Exceeded the max requests limit. Suspending org.eclipse.jetty.server.AsyncContinuation@2145v20 f@REDISPATCHED,resumed,expired


    Do you have any ideas on how to solve the problem?

    Thanks in advance,
    Panos

    This also happens to our multi-server install, zimbra 8.0.5.
    Requests made by our two zimbra proxy machine receive an http 502 error and mailbox.log show:
    2013-12-12 10:26:15,586 WARN [qtp571606922-276216:http://127.0.0.1:80/service/soap/GetInfoRequest] [oip=$zimbra_proxy_ip;ua=zclient 8.0.5_GA_5839;] misc - Exceeded the max requests limit. Suspending org.eclipse.jetty.server.AsyncContinuation@38b8153 b@REDISPATCHED,resumed,expired
    we have already tuned our install following the large installation guidelines:
    zmprov ms mail02 zimbraHttpNumThreads 700
    zmprov mcf zimbraHttpDosFilterMaxRequestsPerSec 100
    but it doesn't solve the problem.
    The only way to mitigate the situation is to restart mailboxd, but after a while (it seems that depends on the average load of the mailbox server) it happens again.
