—log file end—

this all started to happen when i added in a set of new queues. i have
removed the queues but the error persists.

i have done some research and rebasing might be the answer.

if this is the case how to i rebase and will it effect my mysql database?

thank you in advance

Hi Guy

i am running RT4.0.12 using a mysql 5.6.10 under cygwin 2.774 and i am
having a major issue

It’s rather brave to use Cygwin for a production RT instance.

When i try and and reply to a ticket or create a ticket via email i get the
following in the error.log

Your server is running out of memory, likely because the maximum memory
usages of MySQL and Apache aren’t properly configured to coexist
peacefully within the limits of your server. Most people install Apache
and MySQL without tuning them, and then eventually run into problems
like this.

You should read about how to tune Apache and MySQL. Starting with
mysqltuner.pl is a good start, but nothing will do this automatically
for you. You’ll need to manually make changes.

this all started to happen when i added in a set of new queues. i have
removed the queues but the error persists.

The new queues have nothing in particular to do with it.

i have done some research and rebasing might be the answer.

Whatever research you did was mistaken or misleading. “Rebasing” has
nothing to do with MySQL. It is a concept in git, a source code
management tool, used during development. You don’t need to worry about
rebasing.

Thanks Thomas I think this has put me on the right track.

i found and tweeked the mysqltuner.pl to run on mysql database (needed the
host ip address to login into mysql)

This suggested that i increase afew max table/cache values to optimize my
database. i then Optimized all my databases and increase the Virtual memory
on the machine

This has resulted in me being able to send emails from RT again (yeah!), but
the (fork::abort: address space needed by xxx) errors are still sometimes
appearing in the error.log but as of yet have not caused any more disruption

knowing that this will be a ticking time bomb if i leave it in this state,
Do you have any advice on how to tune Apache?

Is there an equivalent ‘Apachetuner.pl’ that you know of as the
mysqltuner.pl was very handly for a beginner like me

management tool, used during development. You don’t need to worry about
rebasing.

Actually rebasing is also a method for aligning the link libraries
addresses in windows so that cygwin can properly emulate fork(2). The
errors he is getting with failure to fork due to conflicting address
layouts in the executable address space may be fixed with a (cygwin)
rebase.

Ahhh. “Today I learned…” :slight_smile: Thanks for the explanation!

Using rebase probably needs to be discussed on the cygwin list as it
has nothing whatsoever to do with RT.

Agreed.

It’s rather brave to use Cygwin for a production RT instance.

Heh. I see the same thing with PostgreSQL sometimes, usually on Stack
Overflow, but also with one particular client.

The upside is that when it’s not a paying client stuck on Cygwin, it’s
easy to fix the person’s problem. “Well, your question starts with ‘I’m
using 9.0.1 on Cygwin’ … there’s your problem.”

Cygwin used to be important, but these days with easy, high performance
VMs and native ports of many open source packages to Windows I no longer
see the appeal.

Rebasing and tunning has done the trick and it is all running fine now

i used the following link to help me rebase

thanks guys for all your support
