Zenoss 3.1.1 --- zenactions MySQL 1114, "The table 'history' is full"

2021-12-29 14:42:41,189 ERROR zen.ZenActions: unexpected exception

OperationalError: (1114, "The table 'history' is full")

I verified that the file system has enough space: 40GB available and I verified that the mysql variable innodb_data_file_path=ibdata1:10M:autoextend has no limits.

Can someone help me to understand why zenoss doesn't clear the alarms?
Thank's in adavance
