Hi
We have about 30 MaxDB instances, mostly v7.8.02.30, but also v7.9.08.06 running on SLES 11 SP2.
DB-Backups are written to an NFS share with automount.
A few weeks ago I realized that some of the databases had full Log Areas, although AutoLog Backup is generally enabled. Due to lack of time and unimportance of the related systems we solved the error by simply re-activating AutoLog which would then run fine for the next 4-7 days.
Now this starts to annoy since it occurs about twice a week and always affects 3 of our databases (both v7.8 and v7.9)
After digging around in the KnlMsg files I can see the following (more or less equal) lines in the affected DBs:
| AUTOSAVE 52024: 49000 pages -> "kup/SID/SID_AUTOLOG.271" | ||
| AUTOSAVE 52024: 55800 pages -> "kup/SID/SID_AUTOLOG.271" | ||
| AUTOSAVE 52002: close error 1 | ||
| SAPDBErr 20003: Any error causes autolog backup to terminate.,_FILE=vkb38+noPIC.cpp,_LINE=5756 | ||
| Backup | 1: Backupmedium #1 (/mnt/dbbackup/SID/SID_AUTOLOG.271) | |
| KernelComm | 6: Backup error occured, Error code 5750 "write_task_crash" |
Now I'd like to know how to track down the error cause. Can you guys help me?
