JDBC driver reconnect question

Hi,

we still have a problem with the database crashing with malloc failures 
(seemingly runnig out of memory) after running for a few days. We have 
investigated some more (after having exchanged operating system version and 
some hardware components) and noticed that the connection pooling algorithms 
of our application server (orion) lead to connections being used for a long 
time. We somehow suspect a memory leak in SAPDB related to connections being 
used for a long time (BTW. is there a way to check that?).

Does the JDBC driver support transparent reconnects of timed out connections? 
If so, we could simply set a very low connection timeout and rely on the JDBC 
driver to reconnect? Is this possible?

Thanks in advance,

Robert
