Package: courier-imap
Version: 3.0.8-13
Severity: normal
I have a strong suspicion that courier-imap is the cause of massive fam
memory leakage on my system. I use courier-imap to manage several huge IMAP
folders on my system (Linux Kernel mailing list, tens of thousands of
messages present at any time), connecting using a Mozilla Thunderbird
client. Every now and then I notice that my system gets _really_ slow,
and then it turns out that famd is using 1.7 GB of memory, using up all
available swap. I can restart it, and it will be small again, but then
it starts growing again over time. The only frequent fam user on this
system is courier-imap, the system is a server machine so it doesn't
usually have any fam connections from desktop programs etc. There are
only two connecting users (it's a home server), so I'm pretty sure the
problem is connected to my own mail workload.
Unfortunately this problem is a bit hard for me to isolate (I don't have
a spare machine to create an isolated test case), but I wanted to report
it anyway, just in case someone recognizes the problem and knows a way
to fix it. I'll try to find a small way to reproduce it at some point,
I'm a bit busy right now so it might be a while. :-/
Cheers,
Bart
