Hi Friends,
We are running some of the Centos 5 32 bit, 5.2 64-bit systems. These
systems are ldap clients and the ldap server is Windows 2003 Server.
Sometimes 1 or 2 services on these servers sucks 100% cpu and the load
becomes high on the server.
Below is an example where one the httpd process was eating 100% cpu
and we took dump of this process
gcore 17711
Core was generated by `/usr/sbin/httpd'.
