Troubleshoot Errors When Syncing All Accounts

In Cortex XSOAR 6.13, fix multi-tenant account sync errors at scale.

When trying to sync all accounts in a large scale environment, the sync fails. The log shows that there are too many open files and the sync fails to open any additional files.

To resolve this issue, update the limit of the number of files on the Cortex XSOAR service level as follows:

1. Open the demisto.service file on each host. It is located at /etc/systemd/system/demisto.service.
2. Under [Service], update the following parameters with a number large enough to avoid the error. if these parameters do not exist, add them.

   • LimitNOFILE
   • LimitNOFILESoft

   For example:

   [Unit]
   Description=Demisto Server Service
   After=network.target
   
   [Service]
   LimitNOFILE=100000000
   LimitNOFILESoft=100000000
   WorkingDirectory=/usr/local/demisto
   Type=simple
   User=demisto
   ExecStart=/usr/local/demisto/server
   EnvironmentFile=/etc/environment
   Restart=always
   RestartPreventExitStatus=29
   
   [Install]
   WantedBy=multi-user.target
                   

3. Reload the daemon.

   systemctl daemon-reload
4. Restart the service.

   systemctl restart demisto
