crash on 5.1 current (Re: FreeBSD 5.1-p10 reproducible crash with Apache2, Postfix locks 5.1-servers?)

Hi,

i have similar problems described in <see subject>.

Two differnet Servers:

A) PIII 1 GHz Dual, Scsi, 1 GB RAM
B) XEON 3.06 GHz Dual, Adaptec SCSI Raid, 4 GB RAM

A runs fine, B crashes once a day between 12 and 24 hours uptime.

B has Apache (2.0.47) with SSL, now i will log incoming https
connections, maybe crashes are related to ssl.
I tested several kernel configuration since about 4 weeks, no luck...
When i stress the system with various tools local or remote, crashes
are very rare or non existent.


- NO SMP + SCHED_4BSD:
results in one crashed apache (others runs fine and serve requests).
Logins via console or ssh freeze after password / motd. No respone
to ctrl-alt-del.

- SMP + SCHED_ULE / SCHED_4BSD
System freezed completely, no responds to ping, keyboard locked up.


Any ideas or requests for more information?

bye,
Andy
