This phenomena seems to dissappear, when you: - build XMail _without_ -static (this dements the mail above) - additionally put 'export LD_ASSUME_KERNEL=2.4.1' in your XMail startup script. Looks like the problem here is the same like with XQM Agent: The new threading scheme introduced with RH9 causes unpredictable behavior of multi-threaded applications. Therefore the LD_ASSUME_KERNEL env var exists, which will force the kernel to emulate the old threadiing scheme. Source (read from bottom to top):

It is important for all users running kernel > 2.4.1 which also includes RH8 users with updated kernel to the latest version. |

What is the output of uname -a Replace your export LD_ASSUME_KERNEL=2.4.1 by export LD_ASSUME_KERNEL="2.4.1" Where is your export statement located? In your XMail startup script ? Sure that THIS script is executed? |

[root@sun root]# uname -a Linux sun.os.st 2.4.22 #2 Sun Sep 21 13:50:10 HKT 2003 i686 unknown [root@sun root]# |

Fact is, that you need LD_ASSUME_KERNEL to be set. Please check all other things mentioned above. |

1.17 has a small mem leak, which can cause coredumps under certain conditions. Please use the latest 1.18 pre release: http://www.xmailserver.org/xmail-1.18.tar.gz |

I have not noticed this on my RH 9 install... Maybe because I only have 2 users and not that much traffic? my server has been up 24/7 for the past month and i've been able to send and receive e-mails without a problem. amd k6-2 550mhz w/ 128 megs ram. it would have crashed a lot since it doesn't have much room or CPU power to run it well. i'd love to put in a P4 system but for my low traffic it would be overkill... (although administrating it would be much faster) |

In most cases 1.17 runs stable. But when it crashes, an update to 1.18 is the cure. |
