[Bucardo-general] perl SV memory leak?

[Mitchell Perilstein]

Hi all,

We're running 4.99.7 (PG 9.1.5, solaris) under fair amount of load and 
have been seeing some unreasonable memory growth in some KIDs and 
CTLs.   I slayed a CTL today (manually with a sigusr1) that had grown to 
1.1 Gb--the MCP happily created a new CTL and its child KID, and they 
picked up where they left off, great.

If I poke through the pid dir and examine each process, a few of its 
remaining unslayed friends are still growing (rss and sz are in kb).

Observations:
a. It's not continual growth; it looks spurty; so I'm trying to figure 
out what event might correlate to a growth period.
b. I've started using Devel::Leak but it's nothing concrete yet.
c. Finally, wondering if this DBI leak has ever been encountered here?
