<div dir="ltr"><div><div><div><div><div>We have been getting this error from time to time with our Shibboleth Identity Provider in Tomcat 6 and before you reply to this thread...<br><br></div>1) Yes I know this is caused by a memory leak and can be 'mitigated' by increasing the max permgen size: <a href="https://wiki.shibboleth.net/confluence/display/SHIB2/IdPApacheTomcatPrepare">https://wiki.shibboleth.net/confluence/display/SHIB2/IdPApacheTomcatPrepare</a><br>

<br></div>1) How do you detect or prevent the evil PermGen error beforehand? My understanding is increasing the MaxPermGenSize is only delaying the inevitable memory leak build up.<br><br></div>2) Better yet: Best practices? What have you already done in your architecture to avoid or defeat this kind of issue?<br clear="all">
