A kind of answer from Apple

Well, well.
First Apple (verbally) expressed concern for the matter - and claimed to have analyzed the logs to show 2 (two) problems:
1) A networking protocol problem
2) A problem with the file system.
After careful consideration, Apple has returned (in writing):
Basically the error is a NetInfo failure. That happens when NI hang
which is when the filesystem does.
They suggest that try it without both scsi cards and using ATA drive...
There have been a lot of complaints about SCSI hanging and a t one point
Adaptec stated the 39160 and 29160 were not compatible with MacOS X...
Since then they released newer drivers than the ones we included with OS
X server. So maybe worth a try to update them...
So - Apple has no part in the problem!
However, the reply raises a few other questions:
1) The server acted the same way, when the filesystem was on the internal disk for a period.
2) If the Adaptec drivers incl. in OSX at one point was 'denounced' by Adaptec, why has Apple not released som sort of technote to this effect?
3) '..maybe worth an update...' is just about as uncommitted an answer as possible.
4) Why should it take local Apple Support, European Apple Support and finally some bigbrain in Cupertino so long to figure it out, if the Adaptec problem has been known to all of them for a while?

Probably the filesystem will feel better by an upgrade - but there's no definite indication that this will remedy the problem

PS.: OSX server version 10.1.3 worked a lot better with only one breakdown a week as opposed to the versions on either side of this - that has resulted in breakdowns 3-4 times a day (on a good day) - which is also a bit worrying. Does the Adaptec drives act less faulty on 10.1.3 ? I wonder...

sigh, sigh - and shame on Apple

Let's get a .mac top level domain! As in

ICANN, the Internet Corporation for Assigned Names and Numbers, is inviting proposals for new sponsored top level domains. This may be wishful thinking, but isn't that a chance to push for a .mac top level domain (TLD)? I for one would VASTLY like the idea of having a domain of something.mac --... (0 Replies)

Net::Server::MultiType - Net::Server personality SYNOPSIS
use Net::Server::MultiType; @ISA = qw(Net::Server::MultiType); sub process_request { #...code... } my @types = qw(PreFork Fork Single); Net::Server::MultiType->run(server_type=>@types); DESCRIPTION
Please read the pod on Net::Server first. This module is a personality, or extension, or sub class, of the Net::Server module. This personality is intended to allow for easy use of multiple Net::Server personalities. Given a list of server types, Net::Server::MultiType will require one at a time until it finds one that is installed on the system. It then adds that package to its @ISA, thus inheriting the methods of that personality. ARGUMENTS
In addition to the command line arguments of the Net::Server base class, Net::Server::MultiType contains one other configurable parameter. Key Value Default server_type 'server_type' 'Single' server_type May be called many times to build up an array or possible server_types. At execution, Net::Server::MultiType will find the first available one and then inherit the methods of that personality CONFIGURATION FILE
"Net::Server::MultiType" allows for the use of a configuration file to read in server parameters. The format of this conf file is simple key value pairs. Comments and white space are ignored. #-------------- file test.conf -------------- ### multi type info ### try PreFork first, then go to Single server_type PreFork server_type Single ### server information min_servers 20 max_servers 80 spare_servers 10 max_requests 1000 ### user and group to become user somebody group everybody ### logging ? log_file /var/log/server.log log_level 3 pid_file /tmp/ ### access control allow .+.(net|com) allow deny a.+ ### background the process? background 1 ### ports to bind host port localhost:20204 port 20205 ### reverse lookups ? # reverse_lookups on #-------------- file test.conf -------------- PROCESS FLOW
