Re: [rt-users] Error when sending or reciving mail (fork::abort: address space needed by xxx)
Rebasing and tunning has done the trick and it is all running fine now i used the following link to help me rebase http://cygwin.wikia.com/wiki/Rebaseall thanks guys for all your support Scott -- View this message in context: http://requesttracker.8502.n7.nabble.com/Error-when-sending-or-reciving-mail-fork-abort-address-space-needed-by-xxx-tp54702p54732.html Sent from the Request Tracker - User mailing list archive at Nabble.com.
Re: [rt-users] Error when sending or reciving mail (fork::abort: address space needed by xxx)
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 -- View this message in context: http://requesttracker.8502.n7.nabble.com/Error-when-sending-or-reciving-mail-fork-abort-address-space-needed-by-xxx-tp54702p54715.html Sent from the Request Tracker - User mailing list archive at Nabble.com.

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. 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... :) 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.

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. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training Services

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