When closing any connection over an Oracle 11.2 DB application is frozen. (oracle-instantclient11.2-*-220.127.116.11.0.i386.rpm)
I observed the same behaviour using two different configurations:
Ubuntu 10.10: TOra 2.1.3 (tora-2.1.3-1.el5.i386.rpm using alien to install it)
Fedora 14: TOra 2.1.3 (tora-2.1.3-1.fc14.remi.i686.rpm)
I had to manually resolve some dependencies in both cases, and I create some symlinks to upgraded libraries:
libpq.so.4 -> /usr/lib/libpq.so.5
libssl.so.6 -> /usr/lib/libssl.so.10
I executed the application from the command line (using just "tora") and no log trace appeared until I manually killed the application.
