Shibd process consumes more memory and leads to CPU spike

[pradeep kumar]

Hi,

We have been running our application with Shibboleth 2.3 for last one year
with around 4k user load. Now we have increased our user base up to 20k and
all in a sudden we have observed CPU spike due to shibd process consumes
more memory. The interesting part here is, this happens every day in
between 4-5PM EST. The shibd process alone consumes around 1GB memory when
the CPU spike happens.

P.S. Our application has been used as a intranet hence the user load is
consistent everyday.

Has this been noticed already anywhere? We feel it could be due to
Shibboleth memory leak. Any pointers will be highly appreciated since it
occurs in our production environment.

Here are the system details

OS: Red Hat Enterprise Linux Server release 5.8 (Tikanga)
CPU: Intel(R) Xeon(R) CPU           E5530  @ 2.40GHz
RAM size:16GB

Thanks
Pradeep
