<![CDATA[Upgraded to new version, huge log files and crash after maint.data.purge]]>Hi, I upgraded a site to 1.13.0 and have log files getting extremely large.

also have a crash after Data Purge,

a bunch of the same here.

I have 2 installs at this site. One with modbus only, working fine, but huge logfiles.
One with opc, a little buggy anyway, but it works fine till the purge.

Any ideas?

Thanks,

Jim

At the bottom of the file you should find this:

  &lt;root&gt;
    &lt;level value="info"/&gt;
    &lt;appender-ref ref="async"/&gt;
    &lt;appender-ref ref="stdout"/&gt;
  &lt;/root&gt;

Change "info" to "warn" or "error", depending on what you want in your logs. You can also edit the category tags. See the log4j documentation for more information about the file.

Not sure what the issue with the OPC data source is (i didn't write it). But, out of memory exceptions usually mean that you should allocate more memory to your instance.
