Summary0000587: HTTP status code 500 on different administration sites
DescriptionI get the http error 500 on different administration sites. One time I opened Crawler_p.html then I switched to another site and then I wanted to go back to Crawler_p.html and I got the following message:
"HTTP ERROR 500

Problem accessing /Crawler_p.html. Reason:
Server Error".

Also if I want to create a dump I get the message above. The dumps are in the additional Information section.

Sometimes I also have this errors on other pages but it looks like the server chooses randomly which page has to fail next xD.
Additional InformationMessage when going on Crawler_p.html:
HTTP ERROR 500

Problem accessing /Crawler_p.html. Reason:

    Server Error

I believe that this issue is actually about high memory usage.
I had the same issue. I have worked it around by increasing the java heap memory limit. But now I have another problem - it uses more than 2GB of memory, and I only have 4GB on that server.
