[cx-oracle-users] SEGV

[Lars I. <la...@ib...>]

Dear all,

I am getting a SEGV under load. This was generated using
cx_Oracle-4.1-b1 on Linux, compiled against the full Oracle client 10.1
on Linux (Debian sarge).

The test code is multithreaded. The problem occurred after several hours
of load.

I have updated to cx_Oracle 4.1.2, compiled with the 10.2 instantclient
SDK and am waiting whether the problem raises its ugly head again.

In the meantime, I'll appreciate any ideas or suggestions.
