Depreciation Run fails with out providing a proper error

Hi Experts

I have some where around 14,000 assets in my fixed assets master in SAP B1. Currently it takes 15 hours to run the depreciation. But from December after it runs for 15 hours it shows the status as Posting journal entries but after a while it fails the run saying the depreciation run has been failed and cancelled. But there is no error description. When i check the log file in the %temp% folder also there is no error given.

How can i solve this problem this is critical to our operation, please let me know the settings that i have to check and everything

Thanks & Regards
