This message is received when Double-Take has attempted to allocate kernel memory within its established limits (the current default limitation is 128 megabytes) and finds that there is none available.
This most commonly happens because other software is using up extreme amounts of paged pool kernel memory, preventing others from using it. Updating all of one's filter drivers to the latest version will go far in correcting this. Software that uses filter drivers includes (but is not limited to):
- Remote access software
- Antivirus software
- Server imaging software
- Snapshot software
- Backup software
Many NAS devices also have additional filter drivers running as well. If that does not work, pooltags may be examined to determine which driver is using the greatest amount of memory.
This issue could occur:
1. After a reboot (Check the Uptime of the server - check the availability of the memory and the validity of the message)
2. If there is a defected memory (test the memory as there could be bad blocks)
3. Because of a virus atack (Check if your Antivirus and Spyware are up to date and if your computer was affected by a virus).
