Memory Leak with Failover Feature enabled

Hello NG,

we have a serious memory leak while using the following environment:

• Multithreaded program (up to 30 Threads)
• Database access from all Threads, only OPEN & CLOSE via ODBC
• Oracle 7.1 Client
• Windows 2000 Terminalserver
• Programm connects via ODBC

Test cases:

• SQLNET configuration with two name servers and two servers (Failover) --> big mem leak
• TNSNAMES configuration with two servers (only failover, no name server) --> mem leak
• TNSNAMES configuration with only one server --> no mem leak

btw: if i start the test with only one thread (more than 100 loops)

     there is no memory leak.
     And i run the same program using a Sybase Sql Anywhere Database
     i have no mem leak with 30 Threads.

On Request i could send you the source of the testprogram.

Any suggestions?

P.S. Found a articel in the oracle bug database, that seemed to be

     a similar (the same?) problem. But i'm not sure.

Link to orcale bug database:

Thanks for any help
