[Expectperl-discuss] Expect on linux monopolizes cpu!

[Syamala T. <sya...@or...>]

I have an in house perl application that uses Expect to tail to a legacy
program.
I have it run satisfactorily on multiple platforms.

On linux platforms, I have sean a strange problem. The perl executable
monopolizing
a cpu after a while of execution time. The legacy program is too
loquacious and writes
a lot of stuff on the STDOUT.  Perhaps thousands of lines are being
shown on STDOUT.

The program is running correctly, but unbearably slow!  Slow over 10
times or worse.

The Expect module was Expect 1.12, when problem was discovered.

I have switched from  Expect 1.12 to the latest Expect 1.15. Problem
persists.

[ Basically the perl application uses expect to match from a hoard of
patterns (about 60)
in a loop. ]

Does some body has a clue as to what is going on?
