      Good Morning All,

      We are having Swap Space issues with the version of QDXi Integrator we just upgraded to (v3.8.1P). I found a post on Clovertech from Feb 2004 siting issues with memory leaks, possibly between the host server, hcimonitor daemon and some of the engine modules. The problem was specific to REV5 but we are on REV6 and are still seeing these problems.

      Can anyone tell me if there has been any patches addressing this issue? Or, probably more likely, some kind of maintenance that can help keep the problem in check?

      Any suggestions would be greatly appreciated.

          Hi Alice – We had these memory leak problems on Cloverleaf 3.8.0 and had to bounce all our processes (hcienginestop/hcienginerun) daily to keep the paging space in check.

          We’re now on Cloverleaf 5.3.0 (no patches) and have had these problems to a much lesser extent.  We now only need to bounce two of our 15 processes that have memory leak problems, and only bounce them about 3 times/week.

          One of the leaking processes is an odbc-based interface, and the other is a VPN interface that we had to set up to cycle the threads to/from the VPN every 10 minutes to keep the connections from timing out.  Apparently that thread cycling causes a memory leak too.

          At any rate, other than cycling the processes, we could find no other way to resolve the problem.

          -Glenn
