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}.
