Thread: Sl_log_1 and sl_log_2 not getting truncated.
Hi,
We have recently installed slony and tsrted replication on one of our test machines. When we start inserting data in to the replicated database, the replication is taking properly. Over a period of time the lag increases between the two database.
Looking further we found that, sl_log_1 and sl_log2 are not getting truncated. Following are the versions which we are using. Slony has been installed for the first time
Postgres version: 8.3.5
slony version: 2.0.0
Can someone let me know what we should be looking at?
Following is the error which we get:

You should sign up to the Slony list and ask your question there. -- Brad Nicholson 416-673-4106 Database Administrator, Afilias Canada Corp.
