I done it but it's remote server and I have a problem to get valid
crash dump -
last attempt was unsuccessful - I see the only file "minfree"
in /var/crash
This box runs httpd with very simple cgi running for each connection
(cgi written in C++, it gets user data and write in into ndbm to analyze
late)
The only unusual messages in /var/log/messages is
Mar 26 10:52:20 ds101 /kernel: in_rtqtimo: adjusted rtq_reallyold to
2400
Mar 26 11:02:20 ds101 /kernel: in_rtqtimo: adjusted rtq_reallyold to
1600
Mar 26 11:12:20 ds101 /kernel: in_rtqtimo: adjusted rtq_reallyold to
1066
... [ every ten minutes ]
Mar 26 12:43:13 ds101 /kernel: in_rtqtimo: adjusted rtq_reallyold to 27
[ problems, cgi exits with core by sig 11]
Mar 26 21:33:47 ds101 /kernel: in_rtqtimo: adjusted rtq_reallyold to 12
Mar 27 02:07:21 ds101 /kernel: in_rtqtimo: adjusted rtq_reallyold to 10
[ crash ]
This is various stat got from crash point. (not later than 2 mins
before)
