[ScreenOS] Why does 'system crit 00081 Cannot allocate 134217744 bytes of memory' appear in get event



Article ID: KB22508 KB Last Updated: 18 Mar 2013Version: 3.0
This article describes the issue of many system critical events being generated in get event.
Find out why there are system crit 00081 Cannot allocate 134217744 bytes of memory logs in get event.
This issue's root cause is that there are many fragments in memory. When AV scan requests the required memory size, there are not enough memory blocks for use; so it will print to the event log.
There are 2 ways to fix the issue:

  • Upgrade to 6.3R7 or later version; ScreenOS uses the new AV engine after the 6.3R7 release.

  • Decrease the AV maximum content size (set av scan-mgr max-content-size XXX); you can try decreasing this value to check if this resolves the issue.
