Class cache cleanup failing, large blobs.dtsf file

DynaMight Pro
DynaMight Pro

I saw in the logs that the cache cleanup fails with a BUFFER UNDERFLOW error; can this be resolved by increasing the Collector memory assignment?

Also, our client has a blobs.dtsf file of approx. 177GB in size - is there a way to reduce this file i.e. by following steps in KB-484 How to fix a class cache explosion, or should this sort itself out once we resolve the buffer underflow issue?

Client is running dT 6.0.



The latest fixpack of 6.1 will automatically fix your issue of a class cache explosion. 

Thanks Allan, unfortunately they're still on 6.0 and their recent attempt to migrate to 6.1 failed, we're assuming due to a corrupted migration archive so we rolled back to 6.0. They believe the massive blobs.dtsf file could've caused the corruption / failure, so we've been asked to assist them in reducing its size. I assume that file is critical if we want to prevent them having to restart agents?

Yes, that large of a blobs file will cause the migration tool to fail. You will need to manually migrate that collector when upgrading which isn't a big deal.
