[opencms-dev] OpenCMS "sleeps" at night

[John Giammarche]

Hello everyone.

I'm having the following problem: each morning, when I
try to access my OpenCMS installation, it doesn't
answer (nor the administration, nor the published web
page). This is in my production server, so the problem
is kind of serious =). The only solution to the
problem is to restart Tomcat. It then works fine for
6, 8 hours, and then it goes down again.

The only strange thing in my setting is that I'm using
Oracle instead of mySQL (over Linux).

I'm also using dynamic export and hiding
/opencms/opencms by connecting Tomcat with Apache
through a vhost.

Here are the complete specs of my system:

CPU: Pentium IV 2.8 Ghz, HT enabled
RAM: 256 MB
Swap: 1 GB
Kernel:  2.4.21-15.0.3.ELsmp
OpenCMS version: 5.0.1 (Kaitain)
Oracle version: Oracle9i Release 9.2.0.4.0 -
Production
Tomcat version: 4.1.31
Apache version: 2.0.50

The last words of OpenCMS yesterday were:

And I guess it stopped working after that. Or maybe it
was later, I really can't tell.

Well, that's all, I'd appreciate any help.

Thanks in advance!

John
