After applying the parameters on the stack you suggested it did not happen any
longer.
Many thanks for your help!

Hi Stefan thanks for your help,
you got it totally: we have exactly groupOfNames entities with thousand of
correlated users. No problems on increasing the stack size for the JVM, we did
it, hope that it will solve the issue. What is strange (and scary) is that the
groups are never accessed directly from the applications, so I was wondering if
there could be some internal component that periodically checks the entities in
the directory.

Stefan Seelmann commented on DIRSERVER-2340:
Such a stack overflow error also happened to me when I worked on
https://issues.apache.org/jira/browse/DIRSTUDIO-1119 and added more than 10k
member attribute values to a groupOfNames entry. I think we need to change the
recursive algorithm the LDAP coded to an iterative one.
Do you have entries me 1000s of attribute values? (probably groups)
As a workaround you can change the stack size of the JVM using the {-Xss} JVM
flag, default on Linux is 1m so you can try e.g. {-Xss4m}. If you use the
installer that would be configured in the conf/wrapper.conf with a line like
{wrapper.java.additional.1=-Xss4m}.
