[Polarhome] two weeks explanation
Tue, 25 Jun 2002 16:01:46 +0200 (CEST)
as all of you experienced in the last 2 months gate, the polarhome realm
gateway had extremely serious problems with system stability.
System just hanged without any log, it was sometimes extremely slow and
there were quote lot of other symptoms that I could not find any solution.
I've spent lot of time to debug, check, enable/disable services and at
the end I come to conclusion that the problem could be connected with NFS
that polarhome heavily uses during inter host communication.
I thought that might be even hacker attack or some nasty hard disk
Finally RedHat announced that some kernel bug is responsible for this

... and another thing. Even if gate was in very inconsistent state I had
to leave it alone for some (exactly 3) weeks.
One week I was on business trip (polarhome almost lost it's administrator
in Petakh Tikvah explosion in Tel Aviv) and Later on two weeks holiday
I promised to my girlfriend: no laptops, no internet cafes during holiday
(seems I spend to much time with computers). I kept my word. But now when
I know the reason of the problem... I see that I could not make too much
(from Poros, Greece) even if I would have access to computer. gate was
down, therefore rest of the system was unreachable as well.
I am terribly sorry, but I always try to point out that: polarhome is a
non commercial (better call it hobby) association of enthusiasts that
relay on one person, therefore polarhome users should not expect
commercial service quality from polarhome. I and the COPS team and lot of
others work overtime without any compensation, just to have a free and
nice island on the internet.
Hope that polarhome users can accept it as it is.
