java.lang.OutOfMemoryError: unable to create new native thread
DLP Enforce running on Red Hat Enterprise Linux, with ten or more Detection Servers, managed by one Enforce server.
Either situation can cause this issue:
su - root
cat /etc/security/limits.conf
If the protect user is not restricted explicitly, add the following to the limits.conf file to raise the process limit above the default of 1024.
<DLP USER> soft nproc 4096
<DLP USER>
hard nproc 63536
REPLACE the <DLP USER> with your DLP USER (generally the default.)
5. Save the limits.conf
Restart the Enforce server.
