After changing the log partition, did you restart the below service:

Cisco Log Partition Monitoring Tool service under Serviceability -> Network Services

Hi Aman,

Try using the COP file (ciscocm.free_common_space_v1.1.cop.sgn) to clear some space on the common partition. 

Download link for COp file:

The cop was available for 9.1 , will it work in 10.5

[Deepak Rawat]

Be careful in running this cop file because of below reasons:

Hi,

Changing the LogPartitionHighWaterMarkExceeded and LogPartitionLowWaterMarkExceeded threshold values to lower numbers (for example, 30/20) should do the trick.

Please make sure that you set them to 95/90 again after sometime to avoid frequent alerts.

As you would have read in the question, it didn't help. Kept it at 20-30 for 3-4 days... The % increased from 96 to 97.

[Amit Sharawat]

Aman,

You can try the cop file:

 ciscocm.free_common_space_v1.1.cop.sgn

But, incase that does not resolve the issue, you need to :

Go to CDR page and change the Configure Automatic Database Purge

Reboot the server.

The system should be stable after that.

Let us analyze the below output :

I am aware about traces in CM ..and have deleted sdi and sdl traces via CLI as well (although only two files were there, I believe that's because of low & high watermark configuration set to 20-30 right now).

I am not aware of "cardbspace" .. as we can see that is the one occupying most space .. does this give any hints ? I am willing to go into cardbspace and delete some files... but which one ? I am not sure...Does anyone has an idea on this  ? Or, am I looking in wrong direction ?
