    Too many SOAP sessions

    Hi All,

    I am newly install Zextras 1.9.1 Beta Version. I have problem with installation but has been solved with advice from Trantor in here : http://forums.zextras.com/general-in....html#post4944.

    Everything work fine, but suddenly my email server very slowly. I am trying to check mailbox.log and give output like following :
    Code:
    2014-09-17 15:59:25,367 INFO  [qtp509886383-259:https://192.168.1.31:443/service/soap/AuthRequest] [name=ahmad@xxxxxxx.xxx;ip=192.168.1.31;ua=zclient/8.5.0_GA_3040;] session - Too many SOAP sessions, closing SoapSession{sessionId=172, accountId=c59ff451-d38f-4fd8-bf6b-2a81f5e4799e, lastAccessed=2014-09-17 15:58:08,118}

    Hello imanudin11!

    Looks like your server is under heavy load, could you please report the information mentioned in section 3.1 of the "How to report a ZeXtras Suite issue" guide and check your CPU and IO load with `htop` and `iostat`respectively, (or with your dedicated Hypervisor tools if you're running in a virtual environment)?
    Also, knowing the number of mailboxes on your server and the number of concurrent Zimbra Web Client users will be very helpful.

    [EDIT] I've just noticed that the same issue was reported on the Zimbra forums aswell, I'd keep an eye on that thread aswell

    Have a nice day,
    Cine
