We are using Sybase 11.

Sometimes, a process causes a blocking lock on a table, resulting in other processes waiting indefinitely, or until the lock timeout occurs.

However, it is possibly to specify (either server-wide or table-wide) that a blocking lock should automatically be killed/removed after a certain period of time, such as 60 seconds?

Currently, we have to manually delete these blocking locks... (Yes, finding the cause of these blocking locks would be nice, but we have been unable to do so, at least so far). The blocking locks occur once every 2 or 3 days, or about once in every 1 million transactions.
