[Pgpool-general] Cancelled queries or empty results?

[Tom Spivey]

Tried the logging, but there was no sign of a big lag behind.
However, I see an error, which I have no clue about - see the 
'pool_send_and_wait:' error:

2011-02-17 08:22:17 LOG:   pid 49474: pool_send_and_wait: E
rror or notice message from backend: : 
DB node id: 0 backend pid: 9205 statement: P message: portal "" does not exist
2011-02-17 08:24:23 LOG:   pid 49478: Replication of node:1 is behind 
12000 bytes from the primary server (node:0)
2011-02-17 08:24:43 LOG:   pid 49478: Replication of node:1 is behind 
0 bytes from the primary 
server (node:0)

What does "statement: P" mean?

Tried version 3.0.2, but that shows the same behaviour.

Thanks again for your help!
