SQL 7.0 SP4

Any suggestions on ways to debug this issue or leads that should be
examined?

The only lead I found in the SQL logs was the following (Log space info for
tran 0:624598 in database 6), and I have not been able to find any KB
articles on topic.

TIA

I apologize if I've left off a vital piece of information from this
question, so please let me know if there is some additional piece of
information that I can add to this question that would make it actionable.

Thank you.
