Time-out occurred while waiting for buffer latch -- type 4

Hello experts,

We get the following error: A time-out occurred while waiting for buffer latch -- type 4, bp 03CEA8A0, page 1:264572, stat 0x1c0000b, database id: 2, allocation unit Id: 142365570695168/423840547405824, task 0x00AE87A8 : 0, waittime 300, flags 0x80039, owning task 0x00FEC2F8. Not continuing to wait.

The error occurs while trying to perform a batch update of a CRM system from back-office data originating in text files, as part of a multi-step process. The data (say full customer base) are bulk-copied to intermediate tables and then transformed to fields using metadata definitions. The error has occurred 4 times in a row in different points of the process, which has been running without problems for the last four months.

Problem was solved. A few processes that was related with  the update, were suspended and couldn't be killed. Furthermore, a few tables  were storing a history of 15 previous updates and the size of those tables was huge. After cleaning those tables and restarting sqlserver service, everything seem to work fine again.
