[Serusers] ser 0.9.6 memory problems

[Mitya]

Hi All,

I have a SER 0.9.6, and sometimes I have memory allocation problem 
somehow :(


Oct 29 19:58:38 sip ser[23161]: processing REGISTER received from x.x.x.x

As I read in the mailing lists, it occurs, when SER has a lots of live, 
opened transactions.

It's a test SER, I think we did not have any opened transactions (maybe 
the failed ones).

Is there any mechanism in SER, what drops the too old opened (most 
likely failed transactions) transactions ?

Can I get the current used shared memory somehow ?

What else can sause this problem ?

Thanks,
Mitya
