why mogilefsd[monitor] memory usage grows up constantly

[lei]

Hi.
We have installed 2 trackers and 3 storage nodes on 3 host from CPAN
for a few days.
After 10+ days, we noticed that both 2 trackers nodes(4GB RAM) have
run out of memory,
mogilefsd[monitor]/[job_master] used about 850M memory, but we haven't
set any files to
mogilefs during these days,mogilefs domain only contains 200 small
files, this make us confused.

Here are some information for the system:
mogilefs: v2.3
perl: v5.10.0 built for i486-linux-thread-multi

We use innodb tables and system/CPU load is quite low ,storage nodes
seems work fine.
Anyone has idea on this issue? Sorry for the poor english :)

Hey,

What distribution are you using? What versions of the various software
(CPAN modules) do you have?

I've not seen a memory leak like that in quite a while... definitely not
in the monitor code, which hasn't changed in a long time.

We switch MogileFS::Server 2.30 to 2.33 using CPAN update.
We'll watch for a while.
thanks,Dormando.
