This error message is related to limit of HTTPS VS with hardware acceleration enabled.
The limit is different based on mode and the default mode depends on firmware version:
| Firmware version |
Default hardware SSL mode |
Limit of hardware accelerated L7 HTTPS VS |
| before 6.2.0 |
epoll |
16 |
| 6.2.0 and newer |
polling |
64 |
- The limit is for a number of hardware accelerated L7 HTTPS VS, it is still possible to create additional VSes, but it is necessary to disable HW acceleration for it.
- It is possible to disable hardware acceleration on VS by:
# config load-balance virtual-server
edit "<VS name>"
set hardware-ssl-status disable
end
It is possible to disable hardware acceleration globally by:
# config system global
set hardware-ssl-status disable
end
- The hardware SSL mode is not changed by the upgrade.
If it is upgraded from a version before 6.2.0, to a newer version, the mode will remain 'epoll'.
- It is possible to switch the modes between 'epoll' and 'polling', however this can only be done via script.
Open support ticket to switch the modes.
Note:
- It is not possible to switch modes on v7.0 and 7.1.
- 'epoll' mode is completely removed from v7.2 and newer.
