    We have a problem after applying this patch. There is already an open discussion in the forum, only “me toos” so far.

      Please, let us know if there is a quick fix. Manually setting a value on the xml files (for given key), only produces an error about “Malformed rule: zimbraHttpContextPathBasedThreadPoolBalancingFilterRules” in zmmailboxd.out

      Zimbra needs to have access to write to /tmp. So make sure not to set ACLs to prevent Zimbra to write to /tmp

    I came up with a quick fix, as described in the forum, the problem, however, appears to be that during compilation of mailbox server, some variables are not there.
