(1) DISK SPACE

To inspect and address any issues with Disk Space

1. View disk statistics:

   • From the Control Center, click Status > Hosts. Use the Hardware Information and Hardware Status tabs to see total disk space and current usage.

   • From the command line, type system-stats disk_used and system-stats disk_free

2. If disk space is in short supply, you have the following options to free disk space:

   • Delete content informational and content quarantine incidents

   • Delete spam message quarantine items

   • Delete backups in the local backup store

   • Delete excess log and message audit log data

3. For a comprehensive list of options for clearing disk space see the recommended resolution for File write error and Clear disk space checklist.

4. After resolving the current disk shortage, reconfigure Symantec Brightmail Gateway to store less data to prevent this issue in the future. You can also configure alerts to notify you when disk space is low.

   • To limit the amount of log data stored: Administration > Settings > Logs > [Database Log Storage Limits]

   • To set up alerts: Administration > Settings > Alerts > Disk Space

(2) MEMORY ISSUES

To inspect and address any issues with memory consumption

1. View memory statistics:

   • From the Control Center, click Status > Hosts to see memory used and memory free.

   • From the command line, type sys-info. See Adding additional Scanners for a full set of memory related commands.

2. If free memory or free swap are low relative to total memory and swap, restart the Brightmail engine and the MTA.

   To restart the Brightmail engine from either the Control Center:

   • Click Administration > Configuration. Check the Host you want to restart and click Edit. Check the Brightmail Engine and click Stop. Click Start.

   To restart the MTA service from either the Control Center or the command line interface:

   • From the Control Center, click Administration > Configuration. Check the Host you want to restart and click Edit. Check MTA and click Stop. Click Start.

   • From the command line, type: service mta restart

Additionally you may try the following to offset memory drain:

• Add an additional Scanner to help deal with heavy load. See Adding additional Scanners.

• Limit message size accepted by the MTA to minimize memory usage. See Setting limits on nested files

• Limit queue size. You can set the maximum size for each message queue and decide whether to defer messages when the queue is full on the SMTP Advanced Settings page.

  See Troubleshooting the message queue

(3) CONFIGURATION CHANGES

   • Decrease the amount of report data collected

   • Reduce the report data retention levels

   • Increase the frequency of report expunger runs

   • Increase the frequency of incident expunger runs

   • Impose spam quarantine threshold limits or decrease them if they are in effect already

   • Decrease spam quarantine retention limits

   • Increase the frequency of spam quarantine expunger runs
