tnslsnr grows over time

We're running 7.3.4.1.0 on Digital UNIX 4.0B.

When started just over two weeks ago, tnslsnr used 560K resident and 4M virtual, and almost no CPU. I just had to kill/restart it, as it had ballooned to 10M and 132M, respectively, and 95% of the CPU.

The machine is used for one *very* lightweight network application at the moment, so it's not load related.

Called technical support, and they saw nothing wrong with listener.ora, and are researching the problem.

Anyone else observed this behavior (and hopefully, have a fix?)

Thanks for any clues!
