i got this logs...
ExecQuery: COM Error(0x80040E14) Could not allocate space for object 'dbo.EPOEvents'.'PK_EPOEvents_AutoID' in database 'ePO4_PICASSO' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.
where can i delete these files?
your DB is full
do some sql maintenance on the db using SQL tools . if you cant get in after standard maintenance you may have to get rid of some events using queries
if you are using sql express think about migrating to full sql
when you get back in check your scheduled log purges or choose selective events to keep the size down
Please take a look at McAfee support article: KB53607 - Unable to log on to the ePO 4.0 Console (issue: ePO database limit reached)
As already mentioned, the database or disk is likely out of free space.
