Changing the virtual memory limit

The recommended ulimit -v setting, which limits the virtual memory for processes, is unlimited on each of the servers where a Indexing Engine node is installed. To modify the limit, complete the following steps:

Procedure

  1. Log in to the server where a Indexing Engine node is installed using the Indexing Engine user id for that server.
  2. Run the following command in a terminal window:
    ulimit -v
    If the returned value is not unlimited, proceed to step 3. If the returned value is unlimited, proceed to step 7.
  3. Log in to the server as the root user.
  4. Open the /etc/security/limits.conf file.
  5. Modify or add the following lines:
    <user-id> hard as unlimited
    <user-id> soft as unlimited
    where <user-id> is the user id used to install the Indexing Engine on the server.
    To modify the value for all users on this server, modify or add the following lines:
    * hard as unlimited
    * soft as unlimited 
  6. Save your changes.
  7. Repeat for each Indexing Engine instance.
