More information about this bug:

I debugged the server with setting DEBUG=5FISPY=3D2 in notes.ini

The CPU-load goes to 100% when following task is started:

> 13.11.2006 03:54:45 PM RunJava JVM: Mon Nov 13 15:54:45 EET 2006 ISpy:=20
Running garbage collector.

So there seems to be problem with Java garbage collector. Any ideas how to =

fix this problem?

Problems with upgrade from SLES 8 / Domino 6.5x to SLES 10 / Domino 7.02





Firstly I would like to thank you all for quick and accucate answers to my =

previous post with same environment. The problem was with scandinavian
characters and encoding them to UTF-8 characters (got Overflow on one=20
function which was coded suspecing ISO-8859-15 character set).

But there is still one problem remaining: CPU-Load.

top - 09:54:25 up 9 days, 19:47,  7 users,  load average: 1.33, 1.10, 1.03
Tasks: 146 total,   1 running, 145 sleeping,   0 stopped,   0 zombie

22111 notes     16   0  393m  40m  25m S  100  2.0  11:58.60 runjava

The process runjava is a taking 100% of CPU-time. And the stopping of the=20
server is impossible because the http-server task won't=20
stop untill kill -9 signal ..

Any ideas how to start solving this issue? There were some posting on=20
notes.net regarding problems with JVM. Is there any easy way
to change JVM on Domino 7.02?

Some details of environment:

Previous environment:
SuSE SLES 8
Domino Server 6.5.1

New environment:
SuSE SLES 10 (No special patches installed for kernel)
Domino Server 7.0.2

I would appreciate any wise guesses for parameters to tweak or configure.=20
Or experiences from similar actions when upgrading SLES.

BR,

Petja
