My setup is pretty basic, i am running 2 filters: avfilter-1.9 and sa_filter-1.3 the only things mailproc.tab contains for some users is a simple redirect, no custom domain or cmdaliases. fred -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Davide Libenzi Sent: 13 avril, 2004 13:05 To: [EMAIL PROTECTED] Subject: [xmail] Re: XMail 1.18 (FreeBSD/Ix86) -- zombie?

As we've loaded a new freebsd/xmail implementation up with more customers, we're increasingly finding it go zombie on us -- its still running in memory, but no longer accepts connections on either 25/110 I am experiencing the same problem with Xmail 1.18. I've pretty much narrowed the problem down to a FreeBSD issue, most likely a configuration issue related to the hard drives. My recent experience with Ecartis and partition location has cemented my belief that this is a FreeBSD issue and not a Xmail issue. My current solution is to auto-reboot the server at midnight every day (my situation makes this an option) and this seems to completely resolve the issue. It looks like the zombiefication occurred around 3 a.m. or so every night. I am also running sa_filter and av_filter, both on partitions separate to Xmail. Needless to say, I haven't ruled either of those out as potential culprits or parts of the problem. The only thing I'm relatively sure of is that I don't think the problem is Xmail itself. - Ken - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

First, run it under swrap on a non privileged user: http://www.xmailserver.org/swrap.c Second, at the beginning of the main function add something like: srand(time() * getpid() * XXX); alloca(rand() % 2048); where XXX is your random number. Do *not* let XMail to run ecartis as root, since it is not the safest package on Earth. - Davide - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

If your locally written code is inside external programs, that should not be a problem. XMail does a double-fork now, and the grand-child gets re-parented to init when the child exits.
