If you have tried the above suggestions and still receive error messages (out-of-memory, communications error, or streams error) you may need to consider the following solutions:

Try increasing the total swap space allocation on your system. See the WEBES Installation Guide for more information on swap space requirements.

On multiprocessor systems, if you have already tried creating a new log file and still receive processing errors, you may be able to eliminate those errors by forcing the DESTA Director to run on only one processor. When the DESTA Director runs on only one processor it is less susceptible to internal synchronization problems, and as a side benefit, it uses less memory. However, throughput is reduced.

To set DESTA Director to run on only one processor:

  1. Stop the Director (see Section 3.8).
  2. Using any text editor, append the following line to the DESTA.REG file. (The default path for this file is /usr/opt/hp/svctools/desta/config.)
desta.CPUAffinity=t

  1. Restart the Director (see Section 3.7).

Another workaround is to remove the swap space limitation that the Director imposes on itself to prevent it from using too much of the system's swap space. Normally, swap space usage is limited to half of the total swap space allocated by the system. Be aware that this workaround can potentially allow the Director to hang or crash the system if it uses all the available system swap space. The Director process and the available swap space must be monitored during the time this workaround is in place (See Section 2.4 for details on monitoring the Director).

To remove the swap space restriction, use the following procedure:

  1. Stop the Director (see Section 3.8).
  2. In the file /usr/opt/hp/svctools/bin/desta, change the following line:
ulimit -v $ulimitvNEW
To:
ulimit -v $ulimitvOLD
  1. Restart the Director (see Section 3.7).

The change only affects the Director process, not any other WEBES processes such as command-line analysis processes.
