openser 1.3.3 was released 3 weeks ago, so I guess you were running  
previous version before, but it happened again since you upgraded to 
1.3.3, right?

We can spot memory leaks even the "out of memory" message is not 
printed. Just archive the logs (the most important is the shut down 
time) and made them available for download so they can be investigated.

There could be two reasons:
- there is memory leak but happens in some cases that you don't 
reproduce in lab, but they are in the production environment
- you get memory fragmentation

Let's see first the debug messages...

Cheers,
Daniel
