[opencms-dev] OpenCMS crashes down due to a "Too many open files" error.

[Juan Manuel Pittacolo]

We are using OpenCms 5.0.0 in a Tomcat/Oracle platform running on Solaris. The system has about 5000 files. Everytime we run the scheduled indexing process, we get an error like the following:

We suspect the problematic class is net.grcomputing.opencms.search.lucene.CronIndexManager.

The process is running at the dawn, when nobody is using the system.
Any ideas about what could it be?

Thanks in advance.
