The point was, Jay asked - and that was my reply.
I asked because my users are starting to move from web based Squirrelmail to Thunderbird. Thunderbird will benefit from Enhanced IDLE (fam/gamin) support, Squirrelmail will not as it does not use the IMAP IDLE command.
Ok. Our people (up to 1150 of them, a spectacular minority "bright/savvy", most not) use Evo (forced for all gdt LTSP terminal users, unless they discover that they can use webmail, in which case they use our - hmmm ... my - Squerlmail 1.5.1 setup, or something of their own on Internet, i.e. Hotmail) or Thunderbird 1.5. Most keep on insisting on using our domain's Squerlmail through web browsers and these latter are inherently lazy weeds, who don't even take the trouble to see what Squerlmail - with my plugins - can offer. Our shop - me - doesn't offer anything than Thunderbird 1.5 or Squerlmail 1.5 to our many Windows WS users ...
If you are only using Squirrelmail, no other clients that support IDLE (Outlook 2000+ and Thunderbird are the two I know of, I'm sure others do though), then I recommend compiling w/o fam/gamin support so that you won't have to deal with the issues they bring to the table (fam/gamin running at 100% CPU usage). But if you have TB/Outlook clients, fam/gamin can reduce CPU usage assuming you get it working right.
Since you started this exchange and I felt bitten, I've looked harder at Courier IMAP (latest) and what it uses of libraries and what they use of services. ldding etc on Courier shows that if I have gamin base and gamin-devel installed and build Courier IMAP, Courier will use the gamin libraries, which call gam_server, whether I want that or not. My entire famd base work has been utterly useless, since it never gets used on RHAS4.
On another note, I have started testing out gamin with inotify support (vanilla linux kernel 2.6.15.6), I've found that it solves the issues I previously had with fam/gamin eating 100% cpu after some time (especially with large, 100k+ message Maildirs). Everything I've read about the old dnotify service (which is what RHEL4 has by default) has been bad.
They never done that on our Red Hat RHAS4 so-called 2.6.9-34 (update 3) server. The most files I had in a (now I realize it :) gamin-regulated server folder was 27,500, way below your 100,000 but way above your second mark, 10,000. The fact that you even *dare* to employ kernel 2.6.15.6 (15 kernel??? never in the world on a Red Hat supported system - ours have been proved to run 24x7 for many months at a time without rebooting) tickles the fancy that you might be using Centos, rather than Red Hat. --Tonni -- Tony Earnshaw Email: [EMAIL PROTECTED] ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
