    FreeBSD error - Approaching the limit on PV entries

    dpbpc62

      This error happened after an upgrade 8.2.1 on 2150F cluster

       

      Full error below

       

      Approaching the limit on PV entries consider increasingeither the vm.pmap.perproc or the vm.pmap.pv_entry_max sysctl

       

      Has anyone see this error?

       

      Have looked through McAfee KB's and nothing specific.

       

      Thanks

          Hello,

           

          We have seen this a few times recently and has been due to Sendmail being misconfigured. Sendmail would get into a loop where it is sending mail to itself, spawning additional processes until all resources are consumed. It is suggested that the Sendmail configuration is looked at, another option is to limit the amount of processes that Sendmail spawns as a temporary workaround:

           

          There is a setting in both the mailertables on the firewall, to configure these files, go to Policy>Application Defenses>Defenses>Mail (Sendmail) then click on the Sendmail Properties button. The section that is relevant is below:

           

          dnl limit defined by MAX_PROCESSES, sendmail will return

          dnl     421 4.3.2 Please try again later

          dnl in response to the MAIL FROM command.

          dnl This feature requires the psd  server.

          dnl Remove "dnl " from the following line to enable this feature.

          dnl D{MAX_PROCESSES}50

           

          Should be modified to:

           

          dnl limit defined by MAX_PROCESSES, sendmail will return

          dnl     421 4.3.2 Please try again later

          dnl in response to the MAIL FROM command.

          dnl This feature requires the psd  server.

          dnl Remove "dnl " from the following line to enable this feature.

          D{MAX_PROCESSES}50

           

           

          A KB article is being written to document this problem.

            Well it was a 50% fix, it worked on the primary but still getting the error on the Standby, any ideas?

              This may be a configuration element which is not shared across the cluster, so you may find that it is necessary to manually change the configuration on the standby appliance also.

                That would be my best guess, should check the configuration on the standby as well to make sure it syncd.
