Guam broken in Centos 7

[Nik Middleton]

Hi,

When you say you disable Guam, are you simply stopping start on boot up and changing the Cyrus ports?

I must admit, this issue with Guam has a very low visibility  it took me sometime to figure out what the problem was.  This issue should flagged on the main site.  

Regards

    Hi,
    we had already a thread regarding guam.
    After the update 0.9.2-1 to 0.9.2.2 the errors were gone but guam 
    stopped working as it endless looped in a threat never meant to join.
    I cannot debug erlang but a simple strace shows the problem.
    I don't know why erlang is used to do proxying and it seems that the 
    programmers do have real troubles to get it working. (Thunderbird issues 
    etc.).
    Disabling guam and halting the package works for me though.
    I cannot copy your problem with wallace so far i have to admit. (100 
    Users).
    I use debian jessie.
    
    Rgds.
