[opencms-dev] OpenCms or Tomcat crash some times everyday

[Salvador Santander Gutierrez]

Hello, list. I've a big problem. We've installed OpenCms 5.0 in this
machine;
- RedHat Linux 9, with 256Mb of RAM
- java sdk version 1.4.2 ( installed as a rpm )
- Tomcat 4.1.24 ( installed as a rpm ) and it's run with the parameters:
JAVA_OPTS = "-server -Xms128m -Xmx256m -Dencoding.file=ISO-8859-1" ( also I
tryied with -Xmx512m )

I use OpenCms to mantain our intranet site, and it has a great number of
access per day.

The problem is that two or three times per day, tomcat or OpenCms crash and
the server doesn't respond any request. I saw in the list that it would be a
problem with crontable, but I delete the tasks and also I delete in the
database the entry 'crontable' in CMS_SYSTEMPROPERTIES table, but this
didn't solve the problem.

In opencms I didn't find anything bad but in Tomcat log appears this
message: ( I've read in some forums of tomcat that can be that there're so
much connections to database )
