missed cmds under redhat 9.0

I am trying to migrate my rancid collection machine from Solaris 2.8 to
Redhat 9.0. The diffs are working, but rancid logs into each cisco
router 4 times with the errors -

svl0rtr00: missed cmd(s): show diag,show install active,show controllers
cbus
svl0rtr01: missed cmd(s): show diag,show install active,show controllers
cbus
svl0rtr02: missed cmd(s): show diag,show install active,show controllers
cbus

When I look at the raw dialog, I see the commands are there -

Entry=13: Addr=FFFF.FFFF.FFFF^M
Entry=14: Addr=FFFF.FFFF.FFFF^M
Entry=15: Addr=0000.2100.0000^M

This setup worked great under solaris, and it still works well for the
foundry and extreme gear.

Here's the versions
solaris redhat
OS 5.8 9.0
rancid 2.2.2 2.2.2
perl v5.6.1 v5.8.0
expect 5.38.0 5.38.0

Any help would be appreciated. It looks like it's in the perl parsing
the output, but I haven't been able to chase it down.

Thanks

The perl "study" command appears to cause the problem in RedHat 9. What I
have determined at this point is that study in a sub (like sub ShowVersion)
causes the regexp not to match when it returns to "main". Therefore a line
in the router config is skipped. Remove "study" from the subs that use it
and the problem will go away. (An alternative is to move study after the
"last" statement which is a few lines later. This only causes the last line
before the next command not to be "studied".)

If you notice, the commands being skipped all follow a command whose output
is parsed by a sub that uses study.

I haven't determined if this is something specific to the way study is used
in rancid or a general RedHat 9/perl 5.8.0 problem.

At least, that worked for me, YMMV,

use of study was a prayer of squeezing a little more out of perl. :)
i have removed them. thanks.
