[Zope] Has anybody run Zope with OpenBSD 2.7 more than a week?

My Zope server is consuming sockets at a speed of 60 sockets/day. This will put my OpenBSD shell without file descriptors in about 16 days. My Zope will crash. My Zope has no much utilization (3 programmers/users at the moment). In a exploitation environment it would crash sooner. 'ulimit' does not solve the problem. When i restart Zope all the jammed sockets are freed, but i would like to have a Zope server whith near to none manual reparations. Do really anybody runs Zope (any version) in OpenBSD 2.7 a long (up)time without failure? I've been more than two months trying it, without success. Please help.
