Need history of previous curtailed EVAs

I'm searching my records for any previous cases where a kink in a water line
(the current 'best guess' for the cooling failure) was so serious that a
Russian EVA was curtailed.

Also, I need a list of other curtailed EVAs and the reasons for them -- I'm
working on that myself, will share when I'm done.

I also am trying to find out how old these two Orlan suits are -- when they
arrived on ISS, and how many EVAs they have already served -- and what
fraction of their warrenty has elapsed.

There also is the possibility of damage during the wiggling and scraping in
the two Pirs-to-Soyuz transfer tests -- it was Kaleri's suit that took most
punishment, because it was used in November when Foale's wasn't, and then
both were used earlier this month in the second test.

Two new suits were sent up on the last Progress.

Are these four Orlans all there are on-board? There are three US EMU's also,
I believe.

As expected, there was substantially radio interference on 121.75 MHz when
ISS was passing over Europe. During airlock depressurization,  I could here
air traffic control conversations clearly, and later during the EVA there
were bad tones and voice-like static.

I'm probably going to write up an assessment for msnbc.com, so any rapid
inputs will be the most valuable.

NASA plans a press conference tomorrow afternoon.

A couple that I can think of are:

Gemini 10.  Both astronauts visors fogged up to the point that
neither one of them could see very well.  Michael Collins
eyes were burning to the point he requested immediate
cancellation of the EVA, but it was his first (of 3?) and
was rather short anyway.

Gemini 11. Gene Cernan gets totally exhaused during his
EVA resulting in early cancellation.

Apollo 15 probably should have been shortened when
one of the astronaut's drinking water system failed, but
he said nothing and was dangerously dehydrated
at the end.

Gemini 9. No doubt well described on NASA's history page.

Thanks, guys. The material went into my 'analysis' on msnbc.com right after
the spacewalk.

...Not exactly. Both Young and Collins had some problems with the air
filtration system, which kept introducing some sort of outgassing that
kept their eyes stinging & watering most fo the tricp.
